Get PriceThe severity of abrasive wear in any system will depend upon the abrasive particle size, shape, and hardness, the magnitude of the stress imposed by the particle, and the frequency of contact of the abrasive particle. In this practice these conditions are standardized to develop a uniform condition of wear which has been referred to as scratching abrasion (1 and 3).

Get PriceFrom coatings to clothing, leather to upholstery, keypads to plastic toys, a product’s ability to resist wear is an important characteristic. There are testing methods relating to the ‘abrasion by friction’ concept. Others are based on the projection of abrasive particles on to the test specimen.
Get PriceTwobody abrasive wear – A form of abrasive wear in which the hard particles or protuberances that produce the wear of one body are fixed on the surface of the opposing body. Wear – Damage to a solid surface, generally involving progressive loss of material, due to relative motion between that surface and a contacting substance or substances.
