Scratch Resistance Testing: A Deep Dive
In Material sciences and engineering, Scratch resistance testing is a big deal. It makes sure that products can handle the use and abuse of everyday use. This article’s all about getting the dirt on scratch resistance testing. We’ll cover why It is significant, the process of doing it, and where it’s used in the everyday life.
Material Hardness
Material hardness is key to how scratch-resistant something is. It’s typically tested using the Vickers and Rockwell hardness tests. Take, for example, when I was making a new cell phone screen. We tested its hardness to make sure it could handle the scratches people might put it through.
Adhesion
Stickiness is how well bonding of surfaces. Good stickiness in the material layers greatly aids with its resistance to scratching.
I once worked on a assignment for a customer trying to strengthen their car’s paint. By making sure the paint adheres more firmly to the subsurface material, we got a superlongevity coating.
Surface Treatment
Stuff for example coatings, anodic oxidation, or polishing processes can greatly increase material scratch resistance. For example, I remember when we were making a substantial floor treatment for a shopping center. We used this original polyurethane substance that was strong resistance to scratching.
Microstructure
Material assembly process, or their microarchitecture, really affects how much they can withstand scratching. You can improve it via modification the microarchitecture. I worked on a project where we developed a extraordinary scratch-resistant glass, thanks to a clever microarchitecture.
Testing Equipment
You gotta have the suitable tools for doing scratch tests. Things like the Taber Abrasive or Stiffness Gauge are very well-liked in the biz. I remember using a Taber Abrasive to evaluate some latest plastic material for a client. The outcomes were quite remarkable.
