摘要
利用电火花强化技术在合金表面沉积WC92Co8强化层,能够有效改善基体表面性能。采用Ti合金、45钢为基体材料,研究了WC92Co8强化层与基体间的界面行为。认为电火花强化技术可在金属基体表面制造高熔点材料强化层。其中Ti合金强化层表面由TiC相、W_2C相和少量的W组成。显微硬度达到1129 HV,强化层厚度大于50μm。Ti合金表面性能发生质的变化。
WC92Co8 coating produced by electrospark deposi-
tion effectively improves the surface performance of the sub-
strate. The behavior of the interface between the WC92-Co08
coating and the substrate is studied. The high- melting-point
WC92-Co08 is deposited onto the surface of Ti alloy,and the
coating is usually more than 50μm thick. The surface of the
coating is mainly composed of TiC and W_2C besides a small
amount of W,and its micro hardness reaches 1129 HV.The
coating dramatically improves the performance of the substrate.
