Abstract

Fishing boats of fiberglass materials require special care to make the vessel more durable. In the field, often found paint coating ships that have faded and peeling within a few years. Yet it is expected that the vessel can last long to continue to maximize the catch of fishermen. Most of the treatments found on fiberglass boats are light treatments, such as cracks. Cracks from gelcoat and scratches due to impact are maintenance work performed at boat or boat building. The key to fiberglass treatment is how to keep the gelcoat layer of fiber shiny. As is known, layer gelcoat is a very strong layer. But over time, weather changes and exposure to sunlight, this gelcoat layer can fade if not treated properly. In order to avoid these conditions, the most efficient way to do that is coated fiberglass with wax or special polish. Selection of care products for fiber boats also cannot be perfunctory. Certain types of waxes that have anti-ultraviolet rays are highly recommended for treatment. By doing proper maintenance techniques, will make the life of the fiber boat more durable and still look shiny.

Abstract

Hardness test on the alloy Fe-50% at Al with the addition of nickel were prepared by mechanical alloying method. The powder mixture Fe-50at.%Al with the variation adding 0,5at.%Ni, and 2at.%Ni are grinded using High Energy Milling HEM E-3D in Argon condition for 10 hours. To determine the hardness, conducted to take the sample with the certain time duration to each composition. Then, the sample which has been taken is characterization using hardness. The results showed that the highest hardness properties exist in the alloy Fe-50% at Al-0.5% at Ni, amounting to 161.53 HV. The addition of nickel on alloy reduces the hardness properties of the alloy. However, the addition of nickel require a short time to raise the hardness properties.

Abstract

Titanium dan paduannya lebih banyak dipilih untuk pemasangan implan ortopedi karena mempunyai sifat tahan korosi dan sifat mekanik yang jauh lebih baik dibanding baja tahan karat (stainless steel). Namun demikian, penggunaan titanium dan paduannya masih memiliki kekurangan. Salah satunya, ketahanan korosi titanium dapat berkurang di lingkungan asam (pH asam). Penelitian ini bermanfaat bagi dokter ortopedi dalam memilih bahan titanium yang lebih tahan korosi untuk aplikasi ortopedi. Material Ti-6Al-4V ELI (Extra Low Intertitial) dengan diameter 1,2 cm dan ketebalan 2,5 mm dilapisi hidroksiapatit komersil, kemudian diuji rendam (immersion test) dalam larutan Hanks (pH 6,0). Pengujian dilakukan dalam empat variasi waktu (t); 1, 2, 3 dan 4 minggu. Laju korosi dihitung dengan metode pengurangan berat (weight loss). Untuk material yang dilapisi HA, tidak ditemukannya indikasi terjadinya korosi, sedangkan material yang tidak dilapisi banyak ditemukan indikasi terjadinya korosi. Laju korosi meningkat seiring pertambahan masa rendam selama 1, 2, 3 dan 4 minggu. Ini dapat dilihat dari pengurangan berat pada sampel uji, terjadi korosi merata yang terdistribusi secara merata di seluruh bagian permukaan spesimen uji. Korosi merata ini juga disebabkan adanya unsur Carbon (C) yang bersenyawa dengan oksigen (O2) menjadi karbondioksida (CO2). CO2 ini larut dalam SBF, membentuk asam karbonat (H2CO2) yang meningkatkan korosifitas.

Abstract

The hydroxyapatite (HA) layer on the surface of the implant material tends to crack during the sintering process for layer densification. This causes the process of implant union with bone (osseointegration) does not function perfectly in the human body. This study aims to reduce cracking by increasing the adhesion of the HA layer on the surface of the Ti-6Al-4V Extra Low Intertitial (ELI) implant material. The research used the dip coating method to get a thin and even layer. To strengthen the adhesion of the coating, Zirconium Oxide (ZrO2) was added in commercial HA suspension. The test specimens were heated at sintering temperatures of 800 0C, 900 0C and 950 0C with a heating rate of 5 0C /minute. Layer morphology and cracks were seen using an optical microscope. The percentage of layer cracks will be measured using ImageJ software. The results obtained, the addition of ZrO2 can reduce cracks in the HA layer of the surface of the test specimen. The percentage of cracks decrease with the addition of ZrO2 (17% and 20% weight) to the suspension of the HA layer. These result is certainly good for increasing osseointegration in the human body.

Abstract

Ti-6Al-4V Extra Low Interstitial (ELI), one of the types of titanium alloys most widely used for orthopedic implants. However, the downside is that titanium is less bioactive. Therefore, Ti-6Al-4V ELI needs to be coated with hydroxyapatite to obtain good osseointegration in the human body. However, the results of several studies show that there are still many cracks found in the surface layer of hydroxyapatite. This research aims to reduce cracks in the Ti-6Al-4V ELI layer. The trick is to add PVA to strengthen the hydroxyapatite layer. This study uses the Dip Coating coating method. The hydroxyapatite used is commercial hydroxyapatite, nano-sized. This hydroxyapatite will later be mixed with Polyvinyl Alcohol (PVA, 17% and 20% by weight). After the specimens were coated, the sintering process was continued at temperatures of 800 0C, 900 0C and 950 0C. Then, microstructure examination was carried out using an optical microscope and Scanning Electron Microscope (SEM). The research results obtained, the addition of PVA can reduce cracks in the coating of the test specimen. Optimal results were obtained by adding PVA (20% weight), at 900 0C T sintering. The surface of the implant material is evenly coated and no cracks are found.

Abstract

The lack of adhesion bonding of the hydroxyapatite (HA) coating layer on the surface of implant material can cause the coating layer to peel off during implantation and will increase the risk of metallic ion release to human body and may also to increase inflammatory effect and slow down the osseointegration process. In order to increase the adhesion of HA coated Ti-6Al-4V ELI by adding Zirconium Oxide (ZrO2) into the coating layer.The coating process of the HA suspension with addition ZrO2 into Ti-6Al-4V ELI sample surfaces was conducted by using dip-coating method. The samples were then heated at 800, 900, and 950 °C. The improvement of adhesion coating was correlated by calculating the removed area. The low value of removed coating area indicated the adhesion coating is good. The test specimen with the addition of ZrO2, has a removed area fewer than the test specimen without the addition of PVA- ZrO2 has. This shows that the test specimen with the addition of ZrO2 has good coating adhesion.The addition of PVA- ZrO2 to the HA suspension increases adhesion bonding of the coating layer, as indicated by the low removed area as compared to that of without PVA- ZrO2 coating.

Abstract

Ti-6Al-4V Extra Low Interstitial (ELI) is one of the most widely used titanium alloys for orthopedic implants. However, its drawback is that titanium has less bioactive properties. Therefore, Ti-6Al-4V ELI needs to be coated with hydroxyapatite (HA) to achieve good osseointegration in the human body. Nevertheless, several studies have shown that there are still cracks found on the HA surface layer. This research aims to focus on biomedical applications, specifically to obtain strong adhesion of the implant material layer, which is expected to improve osseointegration and reduce inflammation effects from implantation. The research method is experimental (testing), using both qualitative and quantitative methods. The coating method used is the Dip Coating method. Research variables include variations in the weight percentage (wt%) of PVA+ZrO2, and HA suspension, as well as variations in sintering temperatures, 800, 900 dan 9500C. The study results showed that the addition of Polyvinyl Alcohol (PVA) and Zirconium Oxide (ZrO2) in the suspension can reduce cracks on the test specimen layer. Optimal results were obtained with the addition of 20% PVA and ZrO2 weight at a sintering temperature of 900°C. The implant material surface was uniformly coated, and no cracks were found.
