Abstract


The paper presents the results of examinations of the structure and properties of the Al2O3+(NiAl+Ni3Al)+Ni(Cr,Fe,Al)+(Cr-Ni+Cr7C3) layers produced on the nickel alloys by the PACVD method with the participation of trimethylaluminum vapours in gaseous atmosphere. The layers have a high surface hardness of about 1300 HV0.05, and high heat and frictional wear resistance. In order to find the correlation between the structure of the multilayers and their properties, the following examinations have been executed: phase analysis by XRD and XPS, analysis of microstructure by optical and scanning electron microscopes as well as X-ray microanalyser, micro-hardness measurements, corrosion and frictional wear resistance testing.
