Induction hardening is one kind of surface hardening process and can improve the wear resistance of components for the combination of high surface hardness and high toughness core. However, it may contain noticeable amount of retained austenite in the matrix of martensite, affecting the structural and dimensional stability of rails. The research focuses on(More)
The corrosion behavior of the anodized Al alloys in the electrolytes containing different metal ion has been investigated. The galvanic corrosion current of anodized AA6061 aluminum plate and C2800 brass plate couples was measured using a zero resistance ammeter for 8 hours in solution containing 3000ppm of copper sulfate. The corrosion current of AA6061-T6(More)
A white surface soft layer of phosphate coated steels, obtained after the quenching and tempering for increase strength, is a problem in the cold formed parts. This paper discusses the heat treatment effect including atmosphere on the microstructural changes of the phosphate coated steels for clarify the mechanism to the formation of this white layer.
