Abstract
In this paper, the effect of nitrocarburizing treatment on tribological properties of AISI 1045 steel was investigated. This medium carbon steel was used in automotive industry, especially in the manufacture of machine components due to the good mechanical properties and lower cost. Characterization of the surface layer of treated samples was made by optical microscopy (OM), Vickers microhardness test, scanning electron microscope (SEM), and pin-on-disk wear machine. Experimental results showed that the surface layers formed through nitrocarburizing processing at 580 °C (compound layer and diffusion zone) increased the microhardness. It was found also that the nitriding treatment reduced the friction coefficient and improved the wear resistance, where the specific wear rate were decreased to 1/9 was noticed after 10 hours of nitriding time.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
