合金在流化床反应器中的热处理已经进行了超过25年。最近，该技术已被用于表面工程应用中的硬质和/或耐腐蚀层的沉积。本文采用熔盐法在金属镍表面存款沉积硼化物涂层。采用光学显微镜、X射线衍射仪和维氏显微硬度计对涂层的形貌、厚度、硬度和相组成进行了分析。在干磨损条件下评价了涂层的摩擦学性能。所产生的涂层的特征在于良好的均匀性，并且发现在处理期间仅形成Ni 3B（空间群Pnma）。此外。硼化物层改善了镍的摩擦学性能。(C)2002爱思唯尔科技有限公司版权所有。
Heat treatments of alloys in fluidized bed reactors have been carried out for more than 25 years. Recently, this technology has been used for surface engineering applications in the deposition of hard and/or corrosion resistant layers. In the present paper we used FBT to deposit boride coatings on nickel metal. The coatings were examined by means of optical microscopy, X-rays diffraction and Vickers microhardness in terms of the coating's morphology, thickness, hardness and phase formation. The coating's tribological properties were evaluated under dry wear. The as-produced coatings are characterized by good uniformity and it was found that only Ni3B (space group Pnma) was formed during the treatment. Furthermore. the boride layer improved the tribological properties of nickel. (C) 2002 Elsevier Science Ltd. All rights reserved.
