Applications

Cohesion And Adhesion Of Hard Coatings

Varying in their composition, hard coatings are typically used to harden the surface of a product. They can be nitrides (Titanium nitride, TiN), carbides (Tungsten carbide, WC) or other types (Diamond like carbon, DLC). Their functionality goes beyond the simple hardening, some are used to protect against corrosion, reduce the wear of a part or avoid the formation of blood clot on materials in contact with blood. They are applied to many different substrates with many different techniques.

Clear Coat And Paint Testing

Studies have found that 50% or more of consumer complaints regarding the aspect of cars were associated with scratch, mar, and chip imperfections. Therefore, any improvement to the automotive paints would extend the long-term appearance of cars, reduce warranty claims, and increase the resale value. The improvement of scratch-resistant automotive clear coats has become a high research priority in the automotive industry.

Scratch Resistance of Strengthened Glass

Indentation and scratch testers provide new and accurate techniques to analyse scratch resistance of glass for any application. Since its introduction in 2008, the Corning® Gorilla® glass has been an omnipresent glass in the smartphone’s screens. The introduction of the Victus® version of Gorilla® glass in 2020 shows that the development of such materials is a continuous effort. In addition of the consumer electronics that brought them to common knowledge, these products are also used in industrial, automotive, aviation, architectural and pharmaceutical applications.

Scratch Testing of Thermal Spray Coatings

Thermal spraying is a coating technique in which melted material is projected onto a surface to coat it. Compared to other deposition techniques, the thermal sprays offer the ability to cover large area at high deposition rates and provide thicker coatings. Thermal sprays are used in various industries such as aerospace, automobile, marine and heavy machinery. The applications for those coatings cover wear and abrasion resistance, low friction, corrosion protection, altering thermal and electrical conductivity and many others.

Wear Resistance of Screen Protector Tempered Glass

Smartphone screen protectors are most of the time made from tempered glass with a polymer backing. But when searching for one of those screen protectors, the question always arises: which one is better? All the products claim the same hardness and high wear resistance. But are all these tempered glass products truly similar in terms of wear? The main cause of scratches or wear are metallic objects such as keys and dust including sand particles (quartz) that damage those screen protectors the most.

Scratch Hard Coating Quality Control

Different methods of testing have been used for the characterisation of the mechanical properties of hard coatings. Tribological measurements provide useful information on the essential properties related to their final use in real applications. Instrumented indentation testing provides information on hardness and elastic modulus of the coatings. Scratch testing is measuring the adhesion and scratch resistance of coatings and providing unmatched information on the mechanical integrity of the coating-substrate system.

Instrumented Indentation

Hardness testers have evolved over time and they now provide different hardness scales for different materials and applications. A new technique proposed in 1992 called Instrumented Indentation Testing provides both indentation hardness and elastic modulus of the material tested, taking the hardness test a step further.
