ASTM G 73, Practice for Liquid Impingement Erosion Testing—The behavior of solid specimens that are exposed to discrete impacts of liquid may be evaluated by conducting studies according to this standard. Specimens are subjected to hquid sprays or jets and the weight loss (or other metal loss data) is recorded with exposure time. This method presents test apparatus, test specimens, test procedures, and calculations and analysis of erosion resistance.

Multibody impact wear is impact of a multitude of particles, such as sand impinging on a coated surface. These processes are more often called erosion. The particular type is dependent on the form of the eroding particles, which can be particles (eg, sand), slurries (particles suspended in a liquid carrier), and liquids by themselves, or even gases under pressure. These processes are very common for coated substrates. A distinction between erosion and abrasion should be noted. This is because testing is quite different. Solid particle impingement (erosion) refers... 

As noted earlier, cavitation erosion test methods such as the vibratory method (Rg. 6) have also been used to screen materials for service under liquid impingement conditions. 

Plastics are frequently used for applications requiring erosion resistance, but there does not seem to be much activity or interest in the tribology community of the 1990s. However, there are a number of tests that are applied and have been used to rate erosion resistance of plastics. Erosion, by definition, is progressive loss of material fiom a solid surface due to mechanical interaction between that surfitce and a fluid, a multicomponent fluid, or impinging liquid or solid particles (3). The field of erosion is usually separated into a number of forms of erosion liquid erosion, either continuous stream or droplet, solid particle erosion, slurry erosion, and cavitation erosion. Each have separate laboratory tests.
