METHOD OF SURFACE HARDENING OF ARTICLE INVOLVING ELECTRIC-CONTACT HEATING |
| 摘要 |
FIELD: metallurgy. SUBSTANCE: graphite gasket is placed between surface of article to be treated and electrode in close contact with the latter, after which electric current is passed through article, gasket, and electrode. According to invention, gasket represents a plate of elastic graphite with compressibility from 1 to 1000% and maintainability of form from 1 to 95%. EFFECT: reduced power consumption and enabled local introduction of high heat power into surface. 7 cl, 6 tbl, 3 tbl, 3 exy
