All manufacturers understand the necessity of abrasion testing who are interested in producing long lifespan and high-quality products. With numerous testing methods available, it is often difficult to decide the best test with their nuances.
The Importance of Wear Testing
The main reason why companies and manufacturers conduct abrasion resistant testing is to ascertain the quality of products they produce that is consistent in performance, free from defects, and endures through their lifecycle. The ideal thing to do is to analyze the wear resistance of the material. Before user data is available, the downside of this process is that it takes too many years. Additionally, the complexity of monitoring and identifying the influencers can be unwieldy, and the associated cost can be prohibitive. A laboratory test can be appealing because companies compress their product span shorter within a monitored and controlled environment. Moreover, it allows material testing under the same condition in the same manner.
An established test protocol, for many products, is developed to ensure the results can be compared. For this reason, companies can use it to demonstrate that they adhere to the minimum performance standard. The company can also gain the complete advantages by showcasing its performance as compared to its competitor. Testing also has the advantage of evaluating the impact of material or supplier changes before implementation. In this competitive world, it can be appealing to seek lower cost options but have negative consequences on the quality of the products.
While the actual conditions may not be presented or exposed, many real-world conditions can be duplicated to get a higher reproducibility with evaluations. To follow an established method is crucial to ensure your results are both reproducible and repeatable.
The Different Types of Wear Testing Instruments
Many wear testing instruments are used to stimulate different wear mode types. One of them is easy to operate, affordable, and versatile. They include:
- Sliding wear – Is generated from a reciprocating body and occurs between two sliding bodies.
- Double-body abrasive wear – Hard particles are shaken along and enforced against the tested solid surface.
- Mar abrasion – Permanent distortions that might not have ruptured the coating surface. However, they tend to change or disfigure the surface appearance.
- Three-body wear (rolling abrasion) – This occurs when abrasive debris or particles are allowed to roll on the surface as well as contacting the substance.
The first step to determine the instrument type important for your application is to understand the test method used by your industry. However, material advances can out space test methods for development. In such cases, the historic rub tester for ink methods cannot be applied. This leaves companies and manufacturers guessing the type of instrument to use.
The Most Important Factor to Consider when Choosing an Abrasion Tester
For the past century, numerous wear testing materials have been used. Fortunately, a lot of work has been done to develop standardized tests. If you are unsure of where to commence, you can start by contacting associations in the industry to determine the acceptability of a test procedure. Other information sources may include test standard organizations such as ISO and ASTM.
