| titleOfInvention | Method of strengthening tool of high speed steel |
| abstract | FIELD: mechanical engineering, tool manufacture. SUBSTANCE: tool surface is prepared preliminary. Then it specially treated by aqueous solution at the temperature being less than its boiling point. The solution consists of metal containing components and non-metal containing ones for forming strengthening phase. Then it is finally heated up to t indoor -Ac 1 temperature with all operations multiple repeated in the complete process cycle. Final heating is carried out either by cutting the metal difficult to work or by heating in a heating device, in particular, in salt bath at the temperature exceeding 560 C Oxide, metal bearing acid, alkali or salt with concentration within 10 g/l are used as metal bearing component, and thiourea or sulfanol with concentration within from 1 g/l up to their concentration in aqueous suspension are used as non-bearing components. Treatment by the method above results in formation barrier and protective films of low friction coefficient. EFFECT: tool of high wear resistance. 10 cl, 2 tbl |
