Properties of PVD hard coatings
Last 2 to 3 decades application of PVD (physical vapour deposition) hard coatings exponentially grows. However, the use of hard, thin films in the field of machine elements is the exception rather than the rule. The main problem lies in the relatively high contact pressure and the very complex loading of machine components, which demand a hard resistance surface and a tough core. In seminar it ...
متن کاملPVD coatings on aluminium substrates
It is well known that aluminium is today the most widely used metallic material besides steel. The mechanical characteristics of aluminium offer an increasing application field, especially where lightweight constructions are required. The demands for improved characteristics such as higher strength and greater durability are achieved by the development of new aluminium alloys. Continuous effort...
متن کاملAntimicrobial titanium/silver PVD coatings on titanium
BACKGROUND Biofilm formation and deep infection of endoprostheses is a recurrent complication in implant surgery. Post-operative infections may be overcome by adjusting antimicrobial properties of the implant surface prior to implantation. In this work we described the development of an antimicrobial titanium/silver hard coating via the physical vapor deposition (PVD) process. METHODS Coating...
متن کاملFracture toughness of different PVD coatings
Indentat~on technque was used to characterize the mechanical properties (elastic modulus, hardness and toughness) both of PVD coatmgs and autocatallt~c chem~cal deposition ones. TIN and TiCN films m ere respectively depos~ted on a duple.: s t adess steel substrate using PVD technque. moreover a Nip films (P content about 8O6) and a NIPIB,C composite ones were used as comparison materials The ef...
متن کاملNanostructural studies of PVD TiAlB coatings
TiAlB coatings with different compositions were deposited by co-sputtering from TiAl and TiB2 targets onto AISI316 stainless steel substrates at a temperature of 170(C. The stoichiometry and nanostructure have been studied by x-ray photoelectron spectroscopy (XPS), x-ray diffraction (XRD) and transmission electron microscopy (TEM). Analysis of the XPS spectra suggests the presence of phases in ...
