SAND-SLURRY TEST FOR ABRASION RESISTANCE
This test can be used to determine the relative abrasion resistance of 1900 ultrahigh molecular weight (UHMW) polymer, as well as other materials. The test produces a scratching, low-stress type of abrasive action.
SUMMARY OF TEST METHOD
A specimen of the material to be evaluated is rotated simultaneously with a wheel control specimen is a sand slurry to produce accelerated wear. The resulting wear, or abrasion, is measured as weight loss. This measurement is converted to a volumetric loss of material by calculation from the material density.
The volumetric loss of material relative to the steel control (based on an assigned value of 100 for steel) is called Abrasion Index (AI). A value lower than 100 denotes a higher wear resistance than that of steel. The lower the index value, the more resistant the material is to abrasion.
