摘　　要：Adhesion strength is an important target in evaluating the quality of coating layers.The traditional way of adhesion strength test is bonding pull off method for thick layers and scratch test for thin films.The drawbacks of these two methods are discussed in this paper,and an evaluating method for adhesion strength of coating by burying beforehand specimen is proposed.The adhesion strength of samples is measured with two methods.The dispersity of testing data is lower than that in the ASTM C663 79 Standard.Adhesion strength is an important target in evaluating the quality of coating layers.The traditional way of adhesion strength test is bonding pull off method for thick layers and scratch test for thin films.The drawbacks of these two methods are discussed in this paper,and an evaluating method for adhesion strength of coating by burying beforehand specimen is proposed.The adhesion strength of samples is measured with two methods.The dispersity of testing data is lower than that in the ASTM C663 79 Standard.
