CEMENTATION METHOD OF HIGH-SPEED STEEL IN HARD CARBURISER |
| 摘要 |
FIELD: metallurgy. ^ SUBSTANCE: invention relates to metallurgy filed, particularly to surface treatment of steel products from high-speed steels. Cementation method of high-speed steel in hard carburiser includes heating up to saturation temperature, isolation at this temperature with feeding 20-25%-water solution of ethanoic acid at a feeding rate 0.25-1.0 ml of solution for 100 g carburiser per hour and cooling on air. ^ EFFECT: reduction of coefficient of linear expansion. ^ 1 dwg, 1 tbl |
