The bearing is in normal operation; it is gradually worn until it finally loses its working ability and its service life is completed; this kind of natural damage is difficult to avoid. However, if the engine is not properly adjusted, the quality of the lubricating oil is not good, or the operating conditions are bad. Causes the bearing to wear prematurely or present various damages; it is the early damage caused by man-made.
Early damage not only greatly reduces the service life of the bearing; it also affects the normal operation of the engine. According to the experience of diesel engine repair for a long time, the common ways of early damage of the sliding bearing are mechanical damage, bearing cavitation, fatigue pitting, corrosion Wait.

Blister copper (content of 99% copper) was prepared in advance as a thick plate, pure copper flakes as a cathode, with sulfuric acid (H2SO4) and copper sulfate (CuSO4) mixture as electrolyte. After power is applied, copper dissolves from the anode into copper ions (Cu) and moves to the cathode. Upon reaching the cathode, electrons are obtained and pure copper (also called electrolytic copper) precipitates at the cathode. Blister copper impurities in lively copper and zinc with copper will be dissolved as ions (Zn and Fe). Since these ions are more difficult to precipitate than copper ions, electrolysis can be avoided by appropriately adjusting the potential difference during electrolysis. Than the inactive copper impurities such as gold and silver deposition in the bottom of the cell. The copper plate so produced is called "Pure Copper Sheet (T2)" and of high quality and can be used to make electrical products. Sedimented in the bottom of the cell analogy as "anode mud", which is rich in gold and silver, is a very valuable object, remove and then processed with high economic value.
