Experimental Investigation of the Effect of Polyisobutilene Additives to Mineral Oil on Cooling Characteristics

CODEN: MPCACD

Abstract

Results of an experimental study of the effect of polyisobutilene additives to mineral oils I-20A, I-12A, and I-8A on their cooling characteristics are provided. It is shown that a small amount of the polyisobutilene oligomer in mineral oil I-20A (3 %) can completely eliminate a film-boiling process during the quenching of steel parts and make a significantly shorter period of film-boiling during quenching in oils I-12A and I-8A. In this case, a surface of steel parts is cooled intensively and constantly, the part distortion is minimal, and hardness is greater and more consistent. The results of the study were applied to bearing products produced by the Svenska Kullagerfabriken AB (SKF) bearing plant (Lutsk, Ukraine).
