It is well known that damage caused by wear and tear of the mechanical parts always seriously affect the accuracy of machinery. It is very important to improve the material properties of the mechanical elements. Anti-abrasion can improve the durability of machinery and equipment, thereby enhancing industrial competitiveness. Hence, it is important to establish the key technology of wear resistance for the related industries. Since the aluminum-silicon alloys are commonly used on the conditions of severe fretting wear, it is necessary to improve the fretting wear resistance before they are used. Therefore, effects of T6 heat treatment on fretting wear resistance of the aluminum-silicon alloys were investigated in this study. The experimental results of this paper will be very beneficial to the future of precision machinery and vehicle industry to develop more internationally competitive products.

: The use of aluminum silicon alloys as automotive components is growing along with the growing desire to reduce the weight of the components used. However, aluminum alloys still have low mechanical properties, so other processes are needed to increase their hardness, one of them by heat treatment process. This alloy material is commonly used for motorcycle piston. This study aims to determine the effect of heat treatment on mechanical properties and microstructure of Aluminum Silicon A383 using the age hardening method with variations in aging temperature and different holding times. The testing of mechanical properties is done by testing the hardness and thermal conductivity. From the testing results, composition of aluminum alloy A383 composed of 73.30% aluminum, 22.08% silicon and highest hardness 105.9HB at an aging temperature 2000C within 30 minutes and the optimal value of the hardness and thermal conductivity of the aging variations performed are at temperature 2000C at holding time 88 minute. As the aging temperature increases, the hardness of aluminum increases and amount of silicon also increase.

Super duplex stainless steel (SDSS) has excellent mechanical properties and corrosion resistance. However, currently, there are few researches conducted on its fretting wear performance. This paper studies the influence of different heat treatment temperatures and medium environment on the fretting wear performance of SAF 2507 SDSS. Results show that the combined effect of the sigma phase and seawater lubrication can significantly improve the wear resistance of SAF 2507 SDSS. After treated with different heat treatment temperatures, different contents of sigma phases are precipitated out of SAF 2507 SDSS, which improves the wear resistance of the material to different degrees. In addition, the fretting wear performance of SAF 2507 SDSS also relates to the lubrication medium. In air, the friction and wear performance of SAF 2507 SDSS is poor, while in seawater, solution and corrosion products that acted as a lubricant dramatically improve the wear resistance of the material. Under the combined action of heat treatment and seawater lubrication medium, the friction coefficient and wear reduce by 70% and 91%, respectively.

Eutectic aluminum-silicon alloys present high frictional coefficient and a high wear rate due to the low hardness under sliding friction conditions. In this paper, the eutectic aluminum-silicon alloy was textured firstly by micro-milling operations. Then, the micro-textured specimen was subjected to anodizing to fabricate alumina films. The surface topography, surface roughness, and bearing area ratio of micro-textured and anodizing micro-textured specimens were measured and characterized. For the anodizing micro-textured specimens, the surface roughness and superficial hardness increase compared with those for micro-textured ones. Tribological tests indicate that anodizing micro-textured samples present lower friction coefficient of 0.37 than that of flat samples of 0.43 under dry sliding conditions. However, they exhibit higher friction coefficient at 0.16 than that of flat samples of 0.13 under oil-lubricated conditions. The difference between the friction coefficient of anodizing micro-textured and flat samples under dry and oil-lubricated conditions is ascribed to the influence mechanism of surface roughness, bearing area ratio curves, and its relative parameters on the tribological performance of testing samples. The dry sliding friction coefficient has a positive correlation with bearing area ratio curves, while they present negative correlation with bearing area ratio curves under oil-lubricated conditions. The synergy method treated with micro-milling and anodizing provides an effective approach to enhance the dry sliding friction property of eutectic aluminum-silicon alloys.
