Summary of Testing Services
Adhesion Testing (stylus, single point technique)
- sample tested "as is", no pre-test handling and manipulation that affect the results
- provide failure load for chipping, cracking, delamination, etc
- better reproducibility and better comparative test than conventional shear strength testing
- technique can distinguish samples with difference in properties smaller than 1%
Adhesion Testing (tensile mode)
- Peel test
- Pull test
- Seal strength
Coefficient of Friction
- Static and dynamic (kinetic)
- Moving sled on stationary plane technique
- ASTM D1894, G99, G133, G143, G171 and custom setups
Creep, Elastic Modulus & Stiffness
- creep is measured using either instrumented indentation, tensile testing or compression testing
- elastic modulus is measured using either instrumented indentation or tensile testing
- stiffness is measured using instrumented indentation
- instrumented indentation technique can distinguish samples with difference in properties smaller than 0.5%
Fracture Toughness & Cracking
- fracture toughness is measured using instrumented indentation
- scratch testing can also be used to study cracking (crack initiation and propagation)
Hardness - Instrumented Indentation Testing (IIT) - Nanoindentation and Micro Indentation
- bulk materials and coatings
- glass, ceramic, metal, polymer, plastic, composite
- hard, soft, elastic materials
- technique can distinguish samples with difference in properties smaller than 0.5%
Hardness - Micro, Vickers
