Tribological tests: TABER TEST

Category: News
Polymers are also involved in tribological performances as other engineering materials.
In recent years polymers are widely involved in the production of gears, brake systems, wheels and other mechanical components that have to be creep resistant.
The use is described as friction of two objects that causes its deformation and loss of material.
Wear resistance is not an inherent characteristic but it is influenced by tribological system. Field tribological tests are hard to carry out as they are expensive and complex. For that meaning, more simple tests were devised in order to recreate tribological systems in laboratory in order to study a more likely result of the wear process. 

Tests that are widely involved in measuring abrasive resistance are known as Taber test.

We as Plastanalisi want to increase the numbers of tests by providing you with our Taber tribometer (Taber Abraser 5131). This tool allows you to study the abrasion resistance on many kinds of thermoplastic materials.
The abrasive action is obtained by specimen rotation which is disc shaped and placed along the vertical axis while two abrasive wheels rotates on the it. Wheels do a complete cycle on the specimen surface, this process enables us to prove the abrasive resistance of the sample all angles. There are many kinds of wheels at different grades of abrasion and they are involved according to the type of sample and the customer needs. Load weights that are on springs can vary.

The abrasion resistance can be seen as:

• Loss of weight at a given number of cycles;

• Loss of weight during each cycle;

• Number of cycles that are required to obtain given damages.
