Pin-on-disk tests were performed to evaluate the wear behaviour of a 2024 aluminium alloy metal matrix composite (MMC) reinforced with 52 vol.% TiC particles (Al-2024/TiC) in fabricated and thermal-treated (T6) condition. The MMC was produced via pressureless infiltration partially sintered preforms an average particle size 1.1 μm at 1200 °C for 2 h under flowing argon. Microstructural mechanic...

Abstract In contrast to conventional components made from a single material, hybrid multi-material allow the production of load-adapted parts with different materials in structural and functional areas. Hardenable forgeable steels high carbon content are suitable for increasing fatigue wear resistance thus an extension component life. However, equivalent more than 0.6 considered difficult weld ...

The use of aluminum alloys as a material for engineering components that rub against each other is increasing, so it important to know the friction characteristics these alloys. In this study, Aluminum 2024 was given heat treatment with variation in aging time and anodization. Then, wear coefficient tests were carried out using pin tool on disc. effect surface anodization are determine amount t...

In machining of parts, surface quality is one of the most specified customer requirements. Major indication of surface quality on machined parts is surface roughness. Finish hard turning using Cubic Boron Nitride (CBN) tools allows manufacturers to simplify their processes and still achieve the desired surface roughness. There are various machining parameters have an effect on the surface rough...

There is an urgent need for more durable and cost-effective bearing and gear steels for wind turbine applications; yet we are still using traditional steels such as 8620 and 52100 steels, which are inexpensive and have high strength. However, higher corrosion resistance is required for marine application of wind turbines. Our research group developed under NSF funding a series of high strength ...

Abstract Abrasive wear can have a detrimental effect on machinery, especially in the mining and construction industries. To prolong machinery lifetime cut down energy consumption, thorough understanding of abrasive is essential: surface topography measurement interpretation (including form, waviness, roughness) are vitally important. However, potentially crucial influence intricacies tribologic...
