Low carbon steel with content ranging from 0.15% to 0.3% cannot be hardened through quenching and tempering processes there is little no martensitic transformation occurring upon quenching. To improve the surface hardness, carburizing commonly employed. Through this treatment, composition of low-carbon altered by diffusion carbon, resulting in a hard outer casing good wear resistance. This work...

A carbon-supersaturated (CS-) high-speed steel punch was prepared using low-temperature plasma carburizing for fine blanking of pure titanium plates. The bare also as a reference to describe the adhesion and abrasive galling in plates, even single shot. CS-punch free from severe chemical galling, after repeatedly fine-blanking microstructure analysis, element mapping composition analysis demons...

Abstract When checking and cleaning whether there is carbon deposit in the cylinder of gasoline engine, it often time-consuming laborious, process complicated. Once disassembly assembly not place, its service life will be affected. with carburizing agent agent, difficult to fully contact wall, so effect poor easy leave chemical composition engine. In this paper, some common ways engine are stud...

While sulfir in diesel fuels helps reduce friction and prevents wear and galling in fuel pump and injector systems, it also creates environmental pollution in the form of hazardous particulate and S02 emissions. The environmental concern is the driving force behind industry’s efforts to come up with new alternative approaches to this problem. One such approach is to replace sulfur in diesel fue...
