摩擦磨損是一个受到温度、环境、表面状态等很多物理和化学因素影响的錯綜复杂的現象。虽然很早就有人开始了这方面的研究工作,但发展得很緩慢,特別是在一些基本理論問題上,至今还没有取得一致的认識。这种情况和以往缺乏一个有效的試驗方法有很大的关系。自从1944年成功地应用了放射性同位素的試驗方法后,摩擦磨損的研究工作获得了較快的进展。这个方法有着許多优点,应用这个方法可以不必拆卸机器,并且可在很短时間內(相当于以前用一般方法所需时間的70分之一左右)得到很高精度的試驗結果(提高50倍左右),費用也大大节 Friction wear is a complex phenomenon that is affected by many physical and chemical factors such as temperature, environment, and surface condition. Although some people started their studies in this field very early on, they have been developing very slowly. To date, there has been no consensus on some basic theoretical issues. This situation is greatly related to the lack of an effective test method in the past. Since 1944 the successful application of the radioisotope test method, the friction and wear research work has made rapid progress. This method has many advantages. With this method, the machine can be disassembled and very accurate test results can be obtained in a very short period of time (equivalent to about one-70th of the time required by the conventional method) Times or so), the cost is also a big festival
