【Abstract】 オsing the method of orthogonal experiment,the effects of the volume and dilution ratio of the oil sample,the rotation speed of the magnetic disc on the deposition state of wear particles are investigated by means of rotary ferrograph.The results of quantitative and qualitative analysis of the density and distribution of wear particles show that the effect of the dilution ratio of the oil sample is the primary factor,the covered area of the first ring of wear particles in the ferrogram increases as the dilution ratio of the oil sample increases owing to the decrease of viscosity resistance,the effects of the rotation speed of the magnetic disc are not so significant.From the experiments,the optimization of parameters for the operation of making ferrogram with a rotary ferrograph is reached.更多还原
