摘　　要：研制了一种新型膏状的螺栓抗咬死耐高温减摩材料,它是由石墨、硅油、羰基镍粉等原材料经复配、分散加工而成.使用时,涂在螺纹表面,可防止螺栓咬死和锈蚀.通过加热试验、Falex试验、盐雾试验、螺栓咬死试验、辐照试验等对其进行了各项性能检测.结果表明:摩擦因数为0.08～0.105;极压失效负荷达到6450～7784 N、耐温(≥300℃)、抗辐照(≥109rad,γ射线);具有优良的抗咬死和防锈性能.有效期可达10年.A new bolt scuffing resistance friction-reducing material (grease) was prepared, which mainly contain graphite, nickel powder, siloxane fluid and has good performance in preventing bolt scuffing and corrosion. By painting on surface of thread of bolt, with tests of heat, Falex, salt spray, scuffing, radiate, the results show that the prepared material has good characteristics e.g. friction coefficient 0.08-0.105, extreme pressure 6450-7784 N, heat resistance (≥ 300°C), radiate resistance (> 109 rad), and exhibits excellent scuffing resistance and corrosion resistance.
