In order to improve the wear resistance of engineering machinery multi-way valve spool, the external chrome plating process is usually used because the wear resistance of chrome plating is twice that of carburizing and quenching and carbonitriding heat treatment. However, the burr problem caused by chrome plating is difficult to find and deal with, which is more damage than the burr, and there are defects such as chrome chipping, pinholes, pitting, and the like. The metal material appearance modification and strengthening skills are also widely used in the multi-way valve spool of engineering machinery, which has greatly improved it.
When using the data, there is often a contradiction between the high hardness, strength, wear resistance and the tolerance and plasticity of the heart. The improper handling of the two is not a waste of data, or an early failure. The metal surface modification modification skills are not simply heat treatment and corrosion resistance. Mainly through the appearance of data modification and strengthening skills, improve the appearance of strength, hardness, wear resistance, often referred to as appearance hardening (enhancement) skills. The two are related, interspersed, and relatively independent. Recently, many new achievements and new skills of scientific skills, such as vapor deposition, laser skills, and electron beam skills, have penetrated into the exterior engineering, broadening the scale of application of external engineering, and are the key skills for achieving reliability and durability of hydraulic components.
