As these bearings undergo high levels of stress and wear, by applying coating, it will increase its wear resistance and result in a longer service life.
This coating for parts which are subjected to frequent sliding, rolling, impacting or vibration. Coating improve the material’s toughness and reduces tensile stress. Most common materials used are:
Coating for erosive wear is dependent on the severity and type of erosion. For solid impingement erosion at a sallow angle of attach where the wear is similar to that of abrasion, high hardness coatings are required. Common coatings are:
Coating on a soft bearing material allows the embedding of abrasive particles and permits deformation to accommodate some misalignment of the bearing surface. Most commonly used materials are:
