Description

A kind of rust resistance and corrosion resistance quenching medium and preparation method thereof

Technical field

The present invention relates to heat treatment technics, be specifically related to a kind of rust resistance and corrosion resistance quenching medium and preparation method thereof.

Background technology

Quenching is that metal works is heated to more than transformation temperature, and after insulation, in quenchant, quick refrigeration obtains the process of martensitic stucture.By quenching technology, can reach and improve or the object such as the adjustment hardness of workpiece and wear resistance.To avoid workpiece deformation and cracking to the requirement of quenchant (quenching medium) in this process; Quenching medium is easy to cleaning, does not pollute and corrodes workpiece surface; Stable performance, high temperature resistant, ageing-resistant, be not easy to go bad; Be convenient to preparation, transport and store, use safety; Starting material are easy to get, with low cost.

Usually, quenching medium is divided into oil type and the large class of aq. type two by composition.Oil type quenching medium is at present comparatively general, and its shortcoming is that oil product speed of cooling is slow, quenching effect difference and inflammable etc., and simultaneously because oil price is higher, and have certain negative impact to environment, its limitation is comparatively obvious.And aq. type quenching medium has safety, environmental protection, long service life, the advantages such as use cost is low, become the first-selected quenchant of heat treatment industry gradually.But aq. type quenching medium also has water cooling speed fast, easily causes the limitation such as workpiece cracking, the moiety by adjusting quenching medium is needed to overcome above problem.
