Abstract

Thermal spray coating is a material protection process by depositing the coating material on the substrate material. Process parameters such as spray-off distance, surface roughness, and substrate preheat temperature, spray time, voltage, and arc current greatly influence the mechanical and tribological behavior. Selection of appropriate process parameters and coating materials must be carried out to obtain a coating that meets the design requirements. The coating method used is electric arc spray with parameters: spray-off distance of 200 mm, compressor air pressure of 7 bar, voltage of 32 volts, and layer thickness of 1 mm. At the same time, the independent variables are arc currents: 159, 185, and 299 amperes. The substrate material is AISI 1045 steel, PMET 885 intermediate material, and PMET 720 coating material. The tests carried out were observing the microstructure, hardness, wear rate, and corrosion rate. This research shows that the higher the arc current, the better the coating quality. At an arc current of 229 amperes, it is known that the hardness, the wear rate, and the corrosion rate are 398.10 VHN, 8.96 x 10-8 gram/mm2.s, and 0.8911 mpy, respectively. This research's contribution is to provide a reference on the influence of the arc current of the electrical arc spray coating process on the tribological behavior of the surface layer so that suitable for the desired application.

Abstract

Bamboo is a natural material that is widely found in South Banten. Using bamboo as an alternative material for manufacturing brake pads is interesting to research. Bamboo resistance to attacks of organisms is so low that it is necessary to give initial treatment. Preservation of bamboo sticks is done by soaking them in seawater. This immersion is determined for 15 and 30 days. The comparison of the composite constituent composition is 30% bamboo fiber, 28% bamboo particles, 2% zinc, and 40% epoxy resin. Compaction pressure is carried out by 400 kg/cm2 for 10 minutes. The sintering process is carried out at a temperature of 150 °C for 60 minutes. From this research, it is known that the immersion of bamboo stems in seawater tends to decrease the hardness and the wear rate of composites.

Abstract

Laminated composites are composed of multiple layers that work together to achieve specific properties. Several factors influence the strength of these composites, including the quality of the surface layers, the strength of the bonds between layers, the adhesion properties, and the thermal behavior. The adhesive plays a crucial role in connecting the layers to form a laminated composite. This study investigates the effect of environmental exposure on the bond strength between the surfaces of laminated composite layers. The laminated composites are made from mahogany wood and are adhered using PVAc adhesive under a pressure of 2 MPa for 30 minutes. After being prepared, the samples are allowed to sit for several days before being immersed in distilled water, seawater, and vegetable oil. Each immersion lasts for 24 hours. The results indicate that the laminated composites experienced a degradation of mechanical properties following exposure to distilled water, seawater, and vegetable oil. Among these, distilled water had the most detrimental effect on the performance of the laminated composite, while exposure to vegetable oil resulted in relatively insignificant changes to its mechanical properties.
