本文用一定的装置研究轴承钢球(52100和M50钢)发射的外激电子,这些钢球已在Borwoll四球疲劳摩损试验机运转。被试验的钢球间歇地从试验机中取出,去除油污,同时被送至真空室,用紫外线照射。用电子倍增管来检测疲劳试验过程中钢球新表面区域发射的外激电子。旋转钢球以测量外激电子发射与钢球位置之关系,从而确定发射源或多种发射源的位置。本试验的分辨率目前仅限于0.27毫米的扫描宽度。外激电子发射衰减结果表明,随着发射时间缓慢减弱。初步证实,疲劳失效发生在电子发射增强的部位。
In this paper, we study the exoelectrons emitted by the bearing steel balls (52100 and M50 steel) with certain devices. These steel balls have been run on the Borwoll four-ball fatigue tester. The steel ball to be tested is taken out intermittently from the testing machine to remove oil stains and is sent to the vacuum chamber for irradiation with ultraviolet rays. Electron multiplier tubes were used to detect the exoelectrons emitted in the new surface area of the steel ball during the fatigue test. Rotate the ball to measure the relationship between the exoelectron emission and the position of the ball to determine the location of the source or sources of emission. The resolution of this test is currently limited to a scan width of 0.27 mm. The exoelectron emission decay results show that as the launch time slows down. Preliminary evidence shows that fatigue failure occurs at the site of enhanced electron emission.
