Abstract
The authors studied the effects of grain size of chromic oxides and the constituents and blending ratio of fatty acids on the gloss-buffing ability.
The results obtained were as follows.
(1) The optimum buffing effects were given by 0.4-0.5μ of average grain size of chromic oxides.
(2) The most desirable fatty acid to be added to grease-base buffing compounds was myristic acid and its blending ratio was 17%.
(3) 18Cr-8Ni stainless steel was more easily polished than 13Cr or 18Cr steel by the same grease-base buffing compound.
(4) For 18Cr-8Ni and 13Cr steels, there were found almost no differences of polishing between work-hardened metals and annealed ones by the same buffing compound.
