A Study on the Wear Characteristics of Al7075 with Changes in Surface Roughness and Ti Thin Film Deposition Time

Advances in Materials Science and Engineering, 2020
Mechanical parts have a problem of wear when used in extreme environments. Aluminum, most used in the industrial field, is a representative material of light weight, but its wear resistance is not good.

Increase of the wear resistance of carbide layers deposited by Pulsed Laser Deposition in addition with an auxiliary laser [PDF]

arXiv, 2008
Carbides stand out because of their high hardness and wear-resistance. Thus these materials are often discussed for coatings of machine tools etc. Within this work Boron Carbide (B4C) and Carbide (C) thin films were deposited on Si (100) substrates by pulsed-laser deposition technique.

The effects of load on the microstructure and wear behavior of Co–27Cr–22Fe alloy processed by high-temperature nitriding

Journal of Materials Research and Technology, 2023
In this study, high-temperature nitriding was used to improve the surface hardness and wear resistance of Co–27Cr–22Fe alloy in a thermogravimetric analyzer. The high-temperature nitriding treatments were performed at 1200 °C for 3 and 10 h. Subsequently,

Simultaneous strength-ductility enhancement in as-cast Ti6Al4V alloy by trace Ce

Materials & Design, 2022
Impurity elements always play a major role in hindering mechanical property improvement in Ti6Al4V, and specifically most of them e.g. O, P, Cl, and S dissolved in the matrix deteriorate the mechanical properties of Ti6Al4V. This work presents a strategy

Wear and corrosion properties of Mg(OH)$_2$ compound layer formed on magnesium alloy in superheated water vapor [PDF]

arXiv
The wear resistance of magnesium and its alloys is very poor due to their inherent low hardness and poor tribological properties. Improving the wear resistance of magnesium and its alloys plays a significant role in expanding their application range.
