Understanding the Different Types of Abrasion Testing

Author: Released in:2021-03-06 Click:145

Abrasion testing is a necessity for manufacturers who are interested in producing high-quality products with a long lifespan. With a multitude to different testing methods available, each with their own nuances, it can be difficult to decide which test to use.

Why is it important that wear testing be performed?

The primary reason companies conduct abrasion resistance tests is to ensure they are producing a quality product that is free from defects; consistent in performance; and will endure throughout its life cycle.

The ideal solution would be to analyze a material’s wear resistance in actual use. Unfortunately, this approach often takes many years before useful data becomes available.  Additionally, the cost of conducting a field test could be prohibitive and the complexity of identifying and monitoring the influences can be unwieldy.  An accelerated laboratory test is appealing because companies can compress the life span of a product into a much shorter duration within a controlled and monitored environment.  Plus, it allows materials to be tested in the same manner, and under the same conditions.

For many products, an established test protocol has been developed to ensure test results are comparable.  This allows a company to demonstrate they meet a minimum performance standard.  Or testing can help a company gain a competitive advantage by showing how it performs compared to the competition.  Another advantage of testing is to evaluate the impact of supplier or material changes before they are implemented.  In today’s competitive environment, lower cost options may be appealing but have unintended negative consequences on product quality.

While a lab test may not represent the actual conditions materials are exposed to, testing can duplicate many real world conditions allowing you to have higher reproducibility with your evaluations.  And following an established methodology helps ensure your results will be both repeatable and reproducible.

What different types of wear testing instruments are available to manufacturers?

There are numerous instruments available that can simulate different types of wear modes.  Taber’s solutions are versatile, affordable, easy to operate and allow the user to evaluate:

  1. Two-body abrasive wear – hard particles are forced against and moved along a solid surface;
  2. Sliding wear – occurs between two solid bodies and is generated from a reciprocating motion;
  3. Mar abrasion – permanent deformations that have not ruptured the surface of a coating, but tend to disfigure or change the appearance of its surface;
  4. Rolling abrasion (or three-body wear) – happens when abrasive particles or debris are allowed to “roll” between the surface and a contacting substance.

Knowing which test method your industry uses is typically the first step to determining which instrument is right for your application.

However in many cases, material advances are outpacing test method development and historic methods may not be applicable. This leaves many manufacturers guessing which instrument they should be using. Taber Industries is often called upon to lend our expertise in these situations to offer our advice and consultation.

Taber’s two most popular options include our Model 5135 Rotary Abraser and Model 5750 Linear Abraser.  In addition we offer the Model 155 Grit Feeder Attachment, Model 418 Crockmeter, Model 800 Falling Sand Tester, Model 5900 Reciprocating Abraser, Model 6160 Oscillating Abrasion Tester, Model 5800 Heavy Duty Linear Abraser and Model 5820 Webbing Abrasion Tester.

Optional attachments also allow different configurations of these instruments to perform specialized abrasion tests for such products as flexible packaging, magnetic stripe, wire / cable insulation, decorated plastics, plus many more.
