Surface treating ferrous metals - with molten salt bath contg carbonate, cyanate, lithium, potassium, and sodium ions |
| 摘要 |
<p>Ferrous metal articles are treated in order to introduce into their surface layers N and C opt. together with S and P by immersing the articles in a molten salt bath contg. (I) CO3-- and CNO- ions, and (II) L2+ and K+ and/or Na+ ions. Improves the resistance of the articles to abrasion and seizure. The surface layers are non-porous.</p> |
