Experimental Researches of Fe-Cr Alloys and Cu-Zn Alloys Used for Microsurgical Instruments Manufacturing

Article Preview

Abstract:

The purpose of this study was to evaluate the chemical and metallurgical aspects, mechanical properties and hardness of the stainless steel of Fe-Cr alloy, the stainless steel of Fe-Cr alloys coating with Ni and Cu-Zn alloys coating with Ni alloys used for microsurgical instruments manufacturing.In dentistry are develop new materials and methods to obtain microsurgical instruments with complex form and who must to present mechanical resistance, good corrosion and a great cleaning identically like the glass. The new methods to obtain the microsurgical instruments try to realize quickly the complex form with a cost is expensive.Ni coating permit a better corrosion resistance of microsurgical instruments, because of the thin shiny layer protective, resistant and homogenous.Ni coating permit a better wear resistance of microsurgical instruments for long time.
