Abrasion resistance refers to the power of a surface to resist being worn out through friction. Abrasion resistance depends heavily on various factors such as the surface finishing, materials used and compaction. Abrasion resistance testing typically refers to tests conducted on solid surfaces such as composites, ceramics and metals to determine their resistance.
The primary goal of conducting abrasion testing is to ensure that companies produce high quality products which are not only long lasting but also free from any deformities. There are numerous abrasion test methods that can help in producing amazing products with no flaws. The methods are also very secure and reliable. However there are some key considerations that you need to make before choosing the ideal abrasion tester that suits your needs.
Factors to consider before selecting an abrasion tester
For the past few decades, many abrasion tests have been developed. If people are not in the limelight about which abrasion tester to purchase then get plausible information regarding companies that gauge test standards for abrasion materials. Make a choice on an abrasion tester that will perhaps modify the wear system. The factors to put into consideration include;
- Contact pressure
- The velocity of the sliding material
- The materials incorporated
- Sample preparation
Ways to test abrasion resistance
There are a variety of distinct ways in which abrasion resistance testing can be executed. The various ways are highlighted herein.
- Rubber wheel abrasion (ASTM G65)
This is conducted through holding a rectangular test specimen against a rotating rubber wheel and throwing away sand of varying sizes and flow rate. The rubber wheel abrasion tester examines the sliding speed and how smooth or rough the rubber is.
- Pin abrasion (ASTM G132)
This entails using both a reference and controlled material. The pin is well set against the abrasive surface in a vertical manner. The test machine allows movement between the abrasive surface and the covering of the pin.
- Taber abrasion
This is precisely the most superior method used today. It comes in two main models for instance the rotary abraser model 5135 and the linear abraser model 5750. The unique thing about Taber test that makes it more superior is its capacity to process accurate data in the shortest period possible. It does not take long before you can determine the quality of the products.
It basically involves placing a sample on a turntable disc that swivels on a very high speed. The abrasive wheels are then dropped on top of the sample. The Taber test is a very reliable option for companies which operate wear tests simply because the cost of conducting the test process is incredibly cheap. You do not only enjoy acquiring a quality abrasion tester but also getting the tester at an affordable price.
The Taber tester has a wide variety of uses which comprises research and development, material examination and process control among other multiple uses in the industrial works.
Well, abrasion test resistance can be tested using various methods as aforementioned above. Several factors have to be taken into account before deciding on the best abraser test to use. Get to understand the speed of the tester, its accuracy in giving sufficient information regarding the standards of the products being tested, materials incorporated in the tester and the cost of the tester as well to ensure that it conforms to your budget. The benefits of performing abrasion resistance tests is to ensure that all the products are in compliance with the set standards and that the competitive advantage of the products can be improved.
