Abstract

The adherent strength of shearing is an important criterion in evaluating the quality of coating layers, and it is also the foundation to optimize manufacturing. The conventional way of adhesion strength test for thick layers is the pull-off method and lateral shearing method. The drawbacks of these two methods are discussed in this paper, and an evaluating method for coating adherence by beforehand embedded specimen is proposed. The shearing strength of samples is measured with two methods. The scatter band of the testing data is lower than that of the ASTM-C663-79 Standard.
