We successfully formed nanostructured TiN, CrN, and multilayered TiN/CrN coatings on the Ni-Cr alloy using a cathodic arc evaporation (CAE) technique. Coatings were exposed to artificial saliva solutions with two pH of 5 and 8 to investigate their ion release. We measured the surface roughness of produced coatings using atomic force microscope (AFM). CrN coatings exhibited smoother surface, while TiN and TiN/CrN coatings showed surfaces with greater roughness. X-ray diffraction (XRD) and energy-dispersive X-ray spectroscopy (EDS) were used to investigate the microstructure of coated and uncoated Ni-Cr samples. We found that the greatest ion release was apparent for uncoated samples in artificial saliva solutions with two pH of 5 and 8. The least ion release was found for CrN coatings once pH was 8 indicating that the coating performance was affected by pH variation and CrN coatings offered the strongest hindrance against ion release.

我们使用阴极电弧蒸发（CAE）技术在Ni-Cr合金上成功形成了纳米结构的TiN，CrN和多层TiN / CrN涂层。将涂层暴露于pH为5和8的人工唾液溶液中，以研究其离子释放。我们使用原子力显微镜（AFM）测量了产生的涂层的表面粗糙度。CrN涂层的表面更光滑，而TiN和TiN / CrN涂层的表面更粗糙。X射线衍射（XRD）和能量色散X射线光谱（EDS）用于研究镀层和未镀层Ni-Cr样品的微观结构。我们发现，在pH为5和8的两个人工唾液中，未涂覆样品的最大离子释放明显。
