表面技术是正在日益显示其重要性的材料科学的分支。材料的表面常常必须满足与基体材料的性能不相适应的要求。因此兴起了一种将基体材料电镀预处理与气相沉积处理综合应用于表面处理的新技术。采用物理气相沉积工艺(PVD),沉积层坚硬,维氏硬度可达2000～4000 HV0.1。将 PVD 涂层法应用于钯/镍合金表面已显示出最大优越性。即使钯/镍合金(75～80%重量 Pd)涂层为1μm,其耐腐蚀性和抗擦磨性都优于其它涂层。由于这种合金即使涂层
Surface technology is a branch of materials science that is increasingly showing its importance. Often, the surface of the material must meet the requirements that are incompatible with the properties of the matrix material. Therefore, there is a new technology that integrates the plating pretreatment and vapor deposition of the substrate material for surface treatment. Physical vapor deposition process (PVD), the deposition of hard, Vickers hardness of up to 2000 ~ 4000 HV0.1. The PVD coating method has been applied to the palladium / nickel alloy surface has shown the greatest advantage. Even though the palladium / nickel alloy (75-80% by weight Pd) coating is 1 μm, its corrosion resistance and abrasion resistance are superior to those of other coatings. Because of this alloy coating even
