METHOD FOR ULTRASONIC SURFACE STRENGTHENING OF PARTS FROM STRUCTURAL STEELS IN LIQUID MEDIUM |
| 摘要 |
FIELD: metallurgy.SUBSTANCE: part is subject to ultrasonic action in a liquid medium tank with an acoustic radiation source placed in it and having the acoustic vibration frequency fof 20-30 kHz during ?=30-45 minutes with the vibrational displacement amplitude ?=7-40 mcm. At processing of parts from steel 40X the vibrational displacement amplitude is chosen within ?=15-40 mcm.EFFECT: increasing the surface hardness of parts without any deterioration of the surface quality.2 cl, 2 tbl, 22 ex |
