Surface Modification of the AI203 / Zr02 abrasive particles

材料的等离子体处理已被证明是一种非常有效的表面强化技术。 摩擦机械性能。与我们的工业合作伙伴合作，我们计划探索Low的使用 压力等离子体处理磨粒表面，主要是氧化铝或氧化锆，以改善 加入粘结剂和烘烤前单个颗粒的力学和摩擦学性能 形成坚固的砂轮。我们建议沉积硬质防护涂层，如：TiC基、TiN基 而CRN-基于氧化物颗粒，提高了通行费的使用寿命。这些涂层具有比氧化物更高的硬度 颗粒，因此，他们应该延长切割速度和收费FIFE。特别是，我们将调查这一影响 不同的硬质防护涂层对单个颗粒的机械和摩擦学性能的影响。

Plasma treatment of materials has been shown as a very powerful technique to enhance surface tribo-mechanical properties. In collaboration with our industrial partner, we plan to explore the use of low pressure plasma to treat surfaces of abrasive particles, mainly aluminum oxide or zirconium oxide, to improve mechanical and tribological properties of the individual grains prior to mixing with bonding agent and baking to form a solid grinding wheel. We proposed to deposit hard protective coatings such as: TiC-based, TiN-based and CrN-based on oxides particles, to improve the tolls life. Those coatings posses higher hardness than oxides particles, therefore they should extend the cutting speed and toll fife. In particular, we will investigate the effect of different hard, protective coatings on mechanical and tribological properties of individual grains.
