dhesive characteristics of coatings and methods for measuring them

Abstract

The paper presents the analysis of information flows for 1980 to 2009, relying on the MSCI, INIS and Inspec Databases related to the investigations into the bond strength of coatings to the substrate and the methods of adhesion strength measurement. The analysis shows the method of coating separation from the substrate and the scratching method to be the basic methods applied for determining adhesion. About 70% of applications fall on the scratching method. The highest adhesion strengths were obtained when the coatings were deposited from the vacuum arc discharge plasma with a preliminary cleaning of substrate surfaces by high-energy ions of the material deposited (310 MeV for nickel films on kovar substrates).
