摘要
试验研究了不同热喷涂材料涂层强度与厚度的关系，指出热喷涂层是扁平粒子的积层组织，这些粒子在碰撞凝固的过程中，由于不均匀收缩的原因，会产生残余应力，随厚度和积层粒子数的增加，残余应力会叠加。如果涂层没有足够的塑性，残余应力会导致涂层。
The strengththickness relation of thermal sprayed coats of different materials is investigated experimentally in this paper It is demonstrated that the compositions of thermal sprayed coats are the lamellar structures of flat particals, and the particals can build residual stress owing to heaterogeneous contractions in the processes of impact and solidi fication. With the thickness increasing ,the deposited particals will increase, the residual stress would overlap. If the coats, have not enough ductility, the residual stress lead to the decrease of strength of thermal sprayed coats.
