【摘要】：在MG-2000銷(xiāo)盤(pán)式磨損試驗(yàn)機(jī)上考察了TC4/GCr15摩擦體系中,TC4合金的磨損行為.利用SEM、XRD對(duì)合金磨面、剖面形貌及結(jié)構(gòu)進(jìn)行觀察與分析,利用HVS-1000顯微硬度計(jì)測(cè)試磨面至心部的硬度,利用激光共聚焦顯微鏡測(cè)試和觀察磨面的粗糙度及三維形貌.結(jié)果表明:TC4合金的磨面形成了摩擦層,其分為有氧化物摩擦層和無(wú)氧化物摩擦層,無(wú)氧化物摩擦層對(duì)磨面無(wú)保護(hù)作用,合金磨損率較高;有氧化物摩擦層對(duì)磨面具有保護(hù)作用.在600°C,摩擦層中含有大量摩擦氧化物,對(duì)磨面具有最佳的保護(hù)作用,合金磨損率最低,TC4合金具有優(yōu)異的高溫磨損性能.磨面粗糙度和摩擦層中的氧化物數(shù)量密切相關(guān),在600°C,磨面被大量光滑氧化物所覆蓋,磨面粗糙度最低,略高于磨損前的表面粗糙度.
[Abstract]:The wear behavior of TC4 alloy in TC4/GCr15 friction system was investigated on MG-2000 pin disk wear tester. The surface, profile and structure of the alloy were observed and analyzed by means of HVS-1000 microhardness tester, and the roughness and 3D morphology of the wear surface were measured and observed by laser confocal microscope. The results show that the wear surface of the W TC4 alloy has a friction layer, which is divided into oxide friction layer and no oxide friction layer. The non-oxide friction layer has no protective effect on the wear surface, the wear rate of the alloy is high, and the oxide friction layer has the protective effect on the wear surface. At 600 擄C, there are a lot of friction oxides in the friction layer, which has the best protective effect on the wear surface, and the lowest wear rate of TC4 alloy has excellent wear performance at high temperature. The surface roughness is closely related to the number of oxides in the friction layer. At 600 擄C, the grinding surface is covered by a large number of smooth oxides, and the surface roughness is the lowest, which is slightly higher than the surface roughness before wear.
