摘要
A new metal particle monitoring instrument was developed by improving the traditional direct reading ferrography.The precipitation behaviors of sub magnetic particles, magnetic particles, and the mixture of these particles were examined with the instrument. The results show that the precipitation behavior of sub magnetic metal particles of copper and aluminum is not random as it was believed previously. The sub magnetic particles show a distribution in the precipitator tube, almost the same as the deposition curves as the magnetic particles have. The deposition amount of particles is increased in the oil which consists of several different kinds of particles. On the base of these experiments, a new index used for the total quantity of wear was redefined.
