Water soluble cutting and grinding oil solution for superalloy

摘要: PROBLEM TO BE SOLVED: To obtain the subject oil solution capable of suppressing elution cobalt, which is an included ingredient in superalloys, and exhibiting excellent corrosion prevention, thus having no problem such as increasing metals, disturbing smooth operations devices, or like, by containing a specific cyclic amine. SOLUTION: This water soluble cutting grinding for superalloys contains amine selected from formulae I-IV (R hydrogen, 1-4C alkyl, but sum total carbon atoms R 10 at maximum.), preferably content 5-50 wt.% concentration undiluted solution. As amine, piperazine, morpholine N-methylmorpholine are preferable standpoint cost, availability, like. If needed, carboxylic acids, mineral oils, surfactants, extreme pressure agents, can be added to objective A cobalt elusion suppressant benzotriazole, improve suppressive force. The generally used diluting it with 1-20 wt.%.
