- Abstract:
- It’s requested for many products to make a good aesthetic impression. This feeling cannot be permanent of course, but manufacturer takes care of a scratch-resistance coating, as surface appearance is one big part of this impression. The paper discusses new method for the scratch test, as an answer to the industry need for the technique that is quick, reliable and economically acceptable. Hence, new test stand was designed to improve existing methods for economical aspect especially. Construction of this instrument is described. Discussion of strong points is presented but also a list of weaknesses and all factors that were neglected is given.
To prove reliability of this test stand some experiments were carried out. All results were verified using a measurement system to inspect surface roughness and contour. Every scratch was evaluated with this system before the load application on the specimen (pre-scan). Then all scratches were measured at several cross-sections – one cross-section for each load.
New method was compared to the one described in ISO 19252 standard for determining the scratch properties of plastics under defined conditions. Also the instrument itself was compared to the advance scratch tester CETR-UMT. In the last section all planned modifications of this tester are described, considering adjustment to industry needs and flexibility for didactic use at technical schools and universities. - Keywords:
