电弧离子镀制备TiBN纳米复合涂层
Deposition of TiBN Nanocomposite Coatings by Cathodic Arc Plating
摘要
Abstract
The work aims to gather scientific data for industrial production of TiBN coating by preparing TiBN nanocompo-site coating at low temperature in pure N2. TiBN coating was deposited on cemented carbide substrates by using ion source-enhanced cathodic arc ion plating system. Effects of N2pressure on crystal microstructure, morphology, hardness and wear resistance of the TiBN coating were investigated systemically. Facts proved that N2pressure had obvious effects on crystal microstructure, morphology, hardness and friction coefficient of the coating. As the N2 pressure increased, TiN crystal phases in the TiB2coating increased while TiB2crystal phases decreased. The structure of TiBN coating was a composite structure with TiN crystal grains and TiB2 crystal grains embedded in amorphous BN substrate. The microhardness was up to 3150HV at the N2 pressure of 0.5 Pa. For grinding material cemented carbide, The friction coefficient of TiBN coating was nearly 0.4. Ion source-enhanced arc ion plating technology can be used to prepare TiBN coating, a nanocomposite coating of high microhard-ness with nanocrystalline embedded in amorphous substrate. The pressure of N2 should be low during industrial production of TiBN nanocompisite coating.关键词
