近十多年来工程界广泛应用金属喷涂技术,特别是等离子喷涂的涂层,不仅较大地改善了基体材料与涂层的结合力,而且对沉积粒子彼此之间的结合力也有显著的改善。随着用途扩大,精确地测定涂层机械性能就显得更为重要了。涂层-基体结合强度是涂层质量的常规检验指标之一。其测定方法是将等离于喷涂的涂层试样用胶粘剂和另一对偶试样(未喷涂层的)粘接在一起,进行拉伸试验。当胶粘剂对
In recent ten years, extensive application of metal spray technology in engineering, especially plasma spray coating, not only greatly improves the binding force between the substrate and the coating, but also significantly improves the binding force between the deposited particles. As the use expands, it is even more important to accurately measure the mechanical properties of the coating. Coating - substrate bonding strength is one of the common test indicators of coating quality. The test method is that the coating sample separated from the spray coating is bonded to another sample (un-sprayed layer) with an adhesive and subjected to a tensile test. When the adhesive is right
