Laser hardening equipment for cylinder liner
Abrasive wear is caused by heavy dust or carbon deposits in the air. Dust is sucked from the upper part, and the carbon deposits are formed in the upper part, so the upper part of the cylinder mirror is relatively worn. When the engine oil is thrown from bottom to top, the hard particles are affected by gravity, so the lower part of the cylinder is more worn.
Because of this position, the maximum pressure of the cylinder piston ring on the mirror, the upper end of the cylinder with high temperature, abrasion resistance of metals decreased, at the same time, the piston at TDC speed is zero, the oil film is not easy to form, so the lower part of the cylinder wear mirror also larger.
normal wear, piston ring and cylinder mirror friction caused by, also known as friction and wear. The maximum wear position of the cylinder mirror surface is the position of the piston near the first ring at the top dead point, which often forms an obvious step.
The wear of cylinder mirrors is a
