In addition to corrosion resistance testing, major material properties Winsert studies includes:
- Hot hardness
- Wear resistance
- Compression yield strength
- Elastic modulus
- Oxidation resistance
- Corrosion resistance
- Thermal conductivity
- Thermal expansion coefficient
Winsert’s Optical Profilometer has the capability of measuring a surface’s profile and density by providing a 3D areal surface characterization of a component. The image at left shows bushing end wear against a washer.
Winsert’s Scanning Electron Microscope (SEM) & X-Ray Review uses a focused beam of electrons in order to produce high resolution images of a sample’s surface topography and composition. Customized with an extra large chamber, entire specimens can be placed inside and analyzed without having to destroy the sample.
In-House Testing Equipment
01. Instron Tensile Tester
Winsert’s customized instron tensile tester has the unique ability to determine a particular alloy’s tensile strength under more realistic application conditions. The tensile strength can be tested while applying heat during the testing frame.
The testing combined with Winsert’s empirical data, experience, and insight, is used to make the proper material recommendations.
02. Thermal Expansion Tester
Winsert’s thermal expansion tester determines the rate at which a material expands as a function of temperature. This tester can be used for design purposes and to determine if failure by thermal stress may occur.
03. Wear Testers
Winsert has 25 wear testers that perform:
- Pin-on-disk, pin-on-pin, and ring-on-ring testing. The wear testers measure metal-to-metal sliding wear resistance or galling resistance and can simulate the wear process under impact and limited sliding conditions.
- Pin-on-ring oscillation wear testing. This simulates valve shaft against bushing wear during open/close cycles.
- Double crank-arm wear testing. This simulates crankpin (or crankshaft) and bushing wear.
