4Cr5MoSiVl钢制压铸模稀土离子氮碳共渗研究
Study on RE Lon Nitro-carbnrizing Used for 4CrSMoSiVl Casting Mold
摘要
Abstract
This paper studies the RE Ion nitro-carbonizing technology for the 4CrSMoSiVl steel surface treatment by using 4% RE, 520 ℃×2h and 1.05 kPa atmospheric pressure. Performance test results of the 4CrSMoSiVl steel treated layer show that the optimization of these parameters makes the surface hardness, wear resistance, high tem- perature oxidation resistance, thermal fatigue properties and corrosion resistance to be significantly improved. An- other test with using this technology has been done for the 4CrSMoSiVl steel automotive lamp aluminum casting mold. The experimental results show that the treated layer has optimal qualities, which can meet the requirements in practice and its service life can be increased by 3 to 4 times.关键词
