中文摘要:在钻探工程中遇到孔内事故时,经常采用割刀来切割事故钻具,然而在切割事故钻具的同时也会涉及到切割周边岩石的问题。本研究针对刀具切割岩石的复杂工况条件,设计了不同退火温度下的聚晶立方氮化硼(Polycrystalline Cubic Boron Nitride Compact,简称PCBN)复合片对磨Si3N4球的摩擦磨损试验,采用了光学显微镜和X射线衍射仪(XRD)、扫描电子显微镜(SEM)、X射线能谱仪(EDS)等表征方法,分析了退火温度对PCBN的影响和PCBN对磨Si3N4球的摩擦学行为。结果表明:高于800 ℃退火处理,PCBN粘结剂氧化生成TiO2。当800 ℃退火的PCBN对磨Si3N4球时,出现轻微的粘着磨损;900 ℃退火的PCBN对磨Si3N4球时,粘着磨损现象加重;然而,1000 ℃退火处理后,磨痕处磨粒磨损和粘着磨损共存。且PCBN对磨Si3N4球时,摩擦系数与退火温度有关。

Research on tribological properties of polycrystalline cubic boron nitride tools based on drilling tools cutting
Abstract:In order to solve the problem of accidents in the hole encountered in the drilling project, cutters are used for accident drills. However, rocks could be cut when drills are cut. Therefore, the friction and wear tests of polycrystalline cubic boron nitride (PCBN) against the Si3N4 ball are designed at different annealing temperatures based on the complex working conditions. Optical microscope, X-ray diffractometer (XRD), scanning electron microscope (SEM), X-ray energy spectrometer (EDS) were used to analyze the influence of heat treatment on PCBN and the tribological behavior of PCBN against the Si3N4 ball. The results show that: After annealing treatment above 800℃, PCBN binder oxidation generates TiO2. Furthermore, there is slight adhesive wear after PCBN at annealing treatment of 800℃ against Si3N4 ball. Adhesive wear is more serious after PCBN at annealing treatment of 900℃ against Si3N4 ball. However, abrasive wear and adhesive wear coexist after PCBN at annealing treatment of 1000℃ against Si3N4 ball. In addition, friction coefficients of PCBN against Si3N4 ball are associated with the annealing temperatures.
