Results From the Tafel polarization curves, the specimen after coating TiN showed that both anodic polarization curve and cathodal polarization curve were flat, natural corrosion potential moved to the positive way, and passivation interval got longer.

结果 塔菲尔极化曲线图形显示，钴铬合金表面经TiN涂层后表现出阳极和阴极极化曲线低平，自腐蚀电位向正方向移动，钝化区间变长。

Methods: 48 casted Ni-Cr alloy metal specimens (12.0 mm×1.0 mm) were fabricated with ShoFu Vintage Halo porcelain and divided into six groups , eight pieces for each group. They were polished against 200-, 400-, 600-, 800-, and 1,000-grit sandpaper after body porcelain sintered, respectively. The specimens in a sixth group not polished was used as control. Surface roughness and Color parameters of the specimens were measured with a Surface Roughometer EX2154-13 and a spectrocolorimeter respectively.
