Methods used to determine the resistance to wear, abrasion, and scratching

Abrasion Testing: This method involves the use of abrasive materials that are applied to the surface of the material and subjected to mechanical movement to cause wear. Parameters such as weight loss or depth of wear are then measured to evaluate the material’s resistance to wear.

The Taber Abrasion Test uses a rotating platform with attached abrasive wheels or disks that apply a specific load to the surface of the material or product under test. The material is subjected to rotational and sliding movements and the resulting wear – weight loss and depth of damage – is measured. The Taber test is a widely used method for evaluating the abrasion resistance of materials. These testers are also called Taber abraser or Taber abrader.

Scratch Testing evaluates the resistance of a material to scratches and surface damage. Various test methods can be used, such as using a stylus or indenter with known hardness to apply a controlled force to the surface of the material. Scratch depth, weight loss, and visual damage assessment are used to evaluate the scratch resistance of a material.

A special mention should be made of The Linear Taber Abrasion Test.

The Linear Taber Test: Both Abrasion and Scratch Resistance

The Linear Taber Abrasion Test can be considered more versatile compared to the standard Taber Abrasion Test in terms of evaluating both abrasion resistance and scratch resistance. While the standard Taber Abrasion Test primarily focuses on evaluating the material’s resistance to rotational and sliding abrasion, the linear variant incorporates linear or back-and-forth motion, which allows for a wider range of wear and damage to be assessed.

By utilizing linear motion, the Linear Taber Abrasion Test can simulate various types of wear and friction that materials may encounter in real-world applications, including both abrasive forces and scratches. This makes it suitable for evaluating material performance in situations where linear wear or scratching is an issue.

The test results, weight loss, scratch depth and/or colour fastness are evaluated against each other or against standard samples. In this way, the quality of the products is maintained at the proper level during routine quality control, or improved during tests aimed at selecting a more suitable material for the application.

It is important to note that while the Taber linear abrasion test provides valuable information about abrasion and scratch resistance, specialized scratch test methods that specifically focus on scratch phenomena can provide more detailed and accurate results for scratch resistance assessment. Nevertheless, the versatility of the Linear Taber abrasion test makes it a valuable tool for evaluating the durability and wear resistance of materials in a variety of applications.

operation method:

During operation, first cut the material to be tested into samples of specified size, fix the samples on the fixture of the testing machine, then place the wear head on the surface of the sample, and start the linear wear test by adjusting parameters such as load and number of round trips. During the test, the surface of the sample rubs against the wear head, and the friction force and the number of reciprocations gradually increase until the set stop conditions are reached, such as test time, wear amount or wear depth, etc.

The steps to operate the linear abrasion testing machine are as follows:

Prepare the sample: Cut the material to be tested into a sample according to the standard specification.

Install the sample: Fix the sample on the fixture of the testing machine.

Set test parameters: set test parameters such as load, number of round trips, and stop conditions.

Start the test: Start the testing machine and start the test.

End the test: When the test reaches the set stop condition, stop the testing machine and take out the sample.

Check the sample: check the wear on the surface of the sample, record the test data and analyze it.

How to Assess the Test Results when Tested with the Taber Linear Abraser?

As we all know, The Taber Linear Abraser is a universal testing instrument that is compatible with various testing items and testing standards. Different test methods have different judging methods. It is impossible for us to list all evaluation methods here. Based on their commonality, the core evaluation methods mainly include the following two types:

The first method is subjecting the sample to testing for a predetermined number of test cycles and then examining it for changes in appearance or properties, such as color, gloss, hardness, scratch, etc. Or you can compare the abraded sample with a recognized standard template to obtain the test results.

The second method is weighing the mass of the sample before and after the test, then subtracting the mass of the sample after the test from the mass of the sample before the test to get the mass lost during the test to determine its wear resistance. Generally speaking, under the same test conditions for different samples, less mass loss means more wear-resistant, and greater mass loss means less wear-resistant.

In general, the evaluation criteria of this taber linear abraser and taber rotary platform abraser have certain similarities. In actual operation, please evaluate the test results strictly according to the requirements of the standards you follow.
