SURFACE-HARDENED PRECISION WEIGHT AND PROCESS OF MAKING SAME |
摘要 |
<p>A precision weight (1) has greater permanence of mass due to a hardened surface layer that provides greater wear and scratch resistance as well as greater corrosion resistance. The hardened surface layer is a diffusion layer of increased carbon and/or nitrogen concentration resulting from a heat treatment under gas atmosphere.</p> |
