The samples were cylindrical specimens, with the following diameter: The testing program aimed to compare the wear characteristics of the two materials supplied. The original method ASTM D specifies a mean of measuring the resistance to abrasion of flat surfaces of plastic materials in terms of volume loss, by using two alternative methods: The resistance to abrasion is defined according to ASTM D as the ability of a material to withstand mechanical action such as scraping, rubbing or erosion, that tends to remove material from asrm surface.
Therefore, the current test procedure was amended to a particular type of equipment, d12422 used a revolving table fitted with silicon carbide P grade paper.
The test specimens were secured in grip, which was suspended in a circular holder. At the application of the force, the test sample revolved both around its own axis, and in a direction opposites to the revolving table. Subsequently, the samples tested were subject to double circular movement, in order to accelerate the abrasion process.
The force to which the specimen holder was pressed against the revolving table was maintained constant. The test time for all specimens was maintained constant to 20 minutes, as well as the abrasive medium abrasive paper grid.
Instead of measuring the change in volume, the four samples were compared based on change in weight or mass loss. Atsm specimens were prepared such that the height was approximately identical for 4 samples before weighting and commencement of the test.
Two electronic scale capable to read to the nearest 0.
In summary, the test conditions were: Silicon Carbide P Forece: Full cross section Time: Graphic Representation of Abrasion Results. The results showed that the steel material showed double the mass loss, during the abrasion tests, as opposed to the King Roller material.
