利用动载荷轴承装置评估了堆焊层对大型柴油机十字头销轴承抗咬合性能的影响。还通过测量油膜的电阻来评价跑合性能。主要结果是：（1）采用锡结合层镀锡铜堆焊的铝锡轴承的抗咬合性能远高于传统铅基堆焊白金属和铝锡轴承； (2)增加锡铜镀层中的铜含量可有效提高抗咬合性能。然而，如果铜含量变得过高，则磨合性降低，从而导致抗咬合性降低； (3)增加堆焊层厚度有利于提高磨合性，从而提高抗咬合性。然而，如果覆盖层变得太厚，则覆盖层内会发生咬合，从而导致抗咬合性降低。
The influences of the overlay on the seizure resistance of the crosshead-pin bearing for large size diesel engines were evaluated by using a dynamic load bearing apparatus. The running-in property was also evaluated by measuring the electrical resistance of the oil film. The major results are: (1) The seizure resistance of the aluminum-tin bearing plated with the tin-copper overlay using the tin bonding layer is much higher than that of the conventional lead-based overlay plated white metal and aluminum-tin bearings; (2) Increasing the copper content in the tin-copper overlay is effective in improving the seizure resistance. If the copper content becomes too high, however, the running-in property is degraded, thereby causing the seizure resistance to decrease; and (3) Increasing the overlay thickness is advantageous for improving the running-in property, and thereby raising the seizure resistance. If the overlay becomes too thick, however, seizure occurs within the overlay, thereby causing the seizure resistance to decrease.
