Abstract

Porous tantalum has been recently recognized as a conventional orthopedic implant for bone substitute applications besides stainless steel, cobalt-chromium, titanium, and other metallic alloys. Porous tantalum has excellent mechanical and osseointegration properties similar to cancellous bone structure. To optimize the utilization, the dip coating technique was applied to coat porous tantalum with hydroxyapatite (HA). X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques investigate the coating characterization. HA is a bioceramic material that used for bone substitutes due to its chemical and structural similarity to bone minerals. Coated porous tantalum requires the sintering process of porous tantalum to adhere to HA. During the sintering process, various temperatures (650°C, 750°C, 850°C, 950°C, and 1100°C) were used to determine the optimum temperature for porous tantalum coated with HA. The heating rate is 1°C/1 min and the holding time is 60 minutes. The result shows that the optimum temperature of HA-coated porous tantalum is at 850°C. The morphology structure of the HA-coated porous tantalum shows that the adhesion between porous tantalum and HA is in good condition. The element in the HA-coated porous tantalum shows that the existence of HA is high.

Abstract

Biomaterials is an advanced material engineering technology that is used to help heal bone fractures or fractures. Currently, many biomaterials use materials such as titanium alloy, stainless steel, platinum, and chromium, but these materials cannot be degraded naturally so a second operation must be carried out to remove the installed biomaterial. Biomaterials are temporary in nature so when the bone returns to its original state, the biomaterial must be surgically removed. Research was conducted to obtain a design with a material that can be naturally degraded without causing toxicity. Magnesium AZ31B is a recommended candidate as a base material for degradable bone implants. Magnesium AZ31B material, it is expected to reduce or minimize the surgical removal of implant biomaterials. Bone plate geometry  use plate  bone  dimension 150mm x 15mm x 3mm with  variation 10 hole parallel and zigzag as well as with a bolt  bone  dimensions  long 40 mm with pitch 1mm diameter 5mm. Test bending was conducted  with ASTM E290-14 showing  that on plate  bone  hole parallel  with  burden  maximum 33,419 KN with a deformation  maximum of 30.89 mm whereas  for  plate  bone  hole zig zag with the burden  maximum 32,863 KN with  deformation  maximum big as 29.97 mm. From the study  experimental  that  plate  bone  hole  parallel  have  nature  mechanic  more  tall  compared  with  plate  bone  hole zig Zag although  with the difference which is not significant. Whereas on simulation FEA plate bone  hole  parallel  with  burden 33,419 KN get  results total deformation  as big as 31,481 mm with von Mises stress 15,337 MPa, then  for  plate  bone  hole zig Zag with  burden 32,863 KN with total deformation 32.466 mm and von Mises stress as big as 33,948 MPa. In testing by  experiment and simulation FEA plate  bone  hole  parallel  get  difference  around 0.591 mm or 0.94% whereas  for  plate  bone  hole zig Zag in  testing  by  experiment and simulation  get  difference  around 2,893 mm or 4.60%.

Abstract

This article discusses bimetal welding between AISI 1040 steel and AISI 1020 steel using the Shielded Metal Arc Welding (SMAW) method with AWS E 7016 electrodes. The purpose of the study was to evaluate the quality of the welded joint, including the mechanical properties and microstructure of the bimetal welding results. The use of high-strength AISI 1040 steel and AISI 1020 steel with malleable properties aims to produce a joint that optimizes the characteristics of each material. The welding process was carried out with varying current parameters to determine its effect on the welding results. Testing included tensile testing, hardness testing, impact testing, and microstructure analysis. The results showed that variations in welding parameters affected the mechanical properties of the joint and the distribution of microstructures in the weld zone, heat-affected zone (HAZ), and base metal. The optimal welded joint was obtained by setting certain current parameters that produced maximum tensile strength and even hardness distribution. This study contributes to the development of bimetal welding technology, especially for applications that require a combination of mechanical properties of two types of steel.
