Helpful Tips For Abrasion resistance testing

Author:QINSUN Released in:2019-08 Click:862

Abrasion resistance testing must be conducted during or after the manufacturing process to make sure the product meets specifications before shipment. Finally consumer feedback can be monitored and product returns evaluated to make sure testing specifications meet their objective.the following are some helpful hints for Product Abrasion testing.

Whether or not a specific type of abrasion test relates with end-use performance relies on a similarity of abrading mechanisms as well as on the extent to which that mechanism is maintained during the course of the abrasion test.

Abrasion resistance is a combination of the specimen’s basic properties such as hardness, elasticity, strength (tensile, cohesive, and shear strength), toughness and thickness, particularly in the case of wear resistance.

The mechanism of wear relies upon the topography of the counterface abradant. It is desirable in most cases to use an abrasive just once, unless it can be refreshed.

Different types of wear can take place in combination or on various areas of the same component.

Particles responsible for abrasion or erosion are characteristically between 1 µm and 500 µm in size.

Materials may not display the same relative order of resistance to abrasion when tested by different techniques.

Test approaches that lack crucial procedural information could add problems with reproducibility.

When assessing multilayered systems, the substrate plays a significant role. Therefore, care must be taken when assessing the results of tests on various substrate materials.

Humidity and loading systems have an impact on test system dynamics.

Do not simply accept that the wear rate is always a linear function of time or number of contact cycles—it relies a lot on the materials, type of wear, and the contact conditions.

Ensure steady-state conditions are realized. Some materials may need a run-in period.

Extrapolate results only with considerable caution.

Do not use loads that surpass the maximum strength of a material or speeds that can cause a thermal condition on the test specimen.
