METHOD OF SURFACE HARDENING OF STEEL PART CONTAINING DEAD-END CAVITIES |
| 摘要 |
FIELD: machine building.SUBSTANCE: method includes application on parts surface of facing charge, and its heating by HF currents. Prior to the facing charge application the dead-end holes are filled with charge containing 25-35% of boron carbide, 20-15% of flux and 50-60% of high alloyed chromous cast iron. Depth of holes filling is 1/3-1/2 of thickness of facing wearproof layer.EFFECT: increased service life of parts due to creation of unfavourable structures during induction build-up.3 dwg |
