摘要

摘要: 采用超音速火焰喷涂方法在AerMet100钢(A100钢)基体上制备了WC10Co4Cr涂层,研究了不同喷砂条件对AerMet100钢表面粗糙度变化及对涂层与基体结合强度的影响.之后将涂层使用化学方法退除,观察涂层制备对AerMet100钢基体表面状态的影响,分析了粗糙度与涂层结合强度之间的关系.结果表明:AerMet100钢基体不同吹砂工艺产生的表面粗糙度 S_a=0.994~4.983 μm时,超音速火焰喷涂WC10Co4Cr涂层的结合强度均不低于72 MPa.喷涂涂层过程对基体表面状态没有较大影响:基体粗糙度 S_a<2 μm时,喷涂后,基体表面的粗糙度略有降低;基体粗糙度 S_a>3 μm时,喷涂后,基体粗糙度略有升高.超音速火焰喷涂的碳化钨钴涂层与AerMet100钢基体的结合同时存在物理与机械力结合,以前者为主要结合力.

Abstract: WC10Co4Cr coating was produced on the AerMet100 alloy by high velocity oxygen fuel srpaying(HVOF). Effect of grit blasting on surface roughness and bond strength between AerMet100 alloy and WC10Co4Cr coating was studied. Influence of fabrication process for the coating on the surface roughness of the substrate was also investigated. The results indicate that the bond strength between AerMet100 alloy and WC10Co4Cr coating made by HVOF is always above 72 MPa when the roughness (S_a) of the substrate is in the range from 0.994 to 4.983 μm. There is no obviously influence on substrate roughness by spraying coating. The slight decrease in the surface roughness of the substrate after spraying was observed when the original S_a is lower than 2 μm and the increase of roughness is also slight when the original S_a is larger than 3 μm. The physical bonding and mechanical bonding contribute to the bond strength between AerMet100 alloy and WCCo coating, and the first one is the main factor.
