用于高速钢和渗碳硬质合金基体上的(Ti、Al)N、(Ti、Zr)N 和(Ti、Al、V)N 涂层,同化学气相沉积(CVD)和物理气相沉积(PVD)的 TiN 涂层相比,发现其耐磨性有所改进。用 Ti:Al 50:50%(重量比)的靶在高速钢钻头上制备(Ti、Al)N 涂层,在某些情况下,其性能比常规的 TiN 离子镀刀具提高到了3倍,而渗碳硬质合金基体上的涂层,能大大改进刀具的后刀面和月牙洼的磨损,根据切削条件,同 CVD 的 TiN/TiC 相比,其性能也提高到3倍。证实了新的多元硬质涂层制备工艺和涂层性能的基本关系,用平面磁控源和粉末冶金靶研制和试验了工业生产的离子镀沉积工艺。首先介绍了新涂层材料的基本研究和进展。其次描述了双阴极磁控源的溅射离子镀工艺的批炉型和直线型 PVD 涂层的工业应用。最后,通过对不同条件下涂层刀具的磨损试验,展现了多元新涂层的优异的耐磨性。
(Ti, Al) N, (Ti, Zr) N and (Ti, Al, V) N coatings for high speed steel and carburized cemented carbide substrates, chemical vapor deposition (CVD) and physical vapor deposition PVD) TiN coating compared to the wear resistance was found to be improved. (Ti, Al) N coatings on HSS drill bits with Ti: Al 50: 50% (weight ratio) targets have in some cases improved their performance by up to 3 times compared to conventional TiN ion plating tools Carbide cemented carbide substrate coating, can greatly improve the tool after the flank and the crater wear, according to the cutting conditions, compared with CVD TiN / TiC, its performance is also increased to 3 times. The basic relationship between the preparation process of the new multi-layer hard coating and the properties of the coating was confirmed. The planar electrodeposition and powder metallurgy target were used to develop and test the industrial production of ion plating deposition process. First introduced the basic research and development of new coating materials. Secondly, it describes the industrial application of batch-type and straight-line PVD coating of sputter ion plating process with dual-cathode magnetron. Finally, the wear test of coated tools under different conditions shows the excellent wear resistance of the multiple new coatings.
