Thermochemical Surface Engineering of Steels: Improving Materials Performance
Mittemeijer, Eric J.
Somers, Marcel A. J.
Thermochemical surface engineering significantly improves the properties of steels. Edited by two of the world's leading authorities, this important book summarises the range of techniques and their applications. It covers nitriding, nitrocarburizing and carburizing. There are also chapters on low temperature techniques as well as boriding, sheradizing, aluminizing, chromizing, thermo-reactive deposition and diffusion. Reviews the fundamentals of surface treatments and current performance of improved materialsCovers nitriding, nitrocarburizing and carburizing of iron and iron carbon alloysExamines how different thermochemical surface engineering methods can help against corrosion INDICE: About the editors List of contributors Woodhead Publishing Series in Metals and Surface Engineering Introduction Part One:
