Abstract
Objective To accurately determine the interface bonding strength between coating and mold copper. Methods Con-sidering that the casting mold coating belongs to a kind of thick, tough coating ﹠ toughness-based material, a standard shearing strength test method was used to measure its interface bonding strength. It was suggested to measure the bonding strength on coating interface using the series of specific mold with a sample of 1 millimeter in width as established by Mr. Jing Yu-an. Then interface bonding strength of the copper, electroplate layer/copper alloy, spray layer/copper alloy were researched. Results By testing and analyzing, the variance coefficient of shearing strength for copper was the lowest and the variance coefficients measured using Jing′s method were lower than those measured with GB 13222-1991 for all kinds of layers. Conclusion The veracity of Jing′s method was better than that of GB 13222-1991 and it was more suitable for testing the bonding strength of mold copper coating. In order to reduce system errors, the copper′s shearing strength must be tested at first.关键词
