The Gas Jet Erosion Rig is a laboratory testing system designed to evaluate erosion wear behavior of materials and coatings subjected to high-velocity particle-laden gas flow. You use this equipment to simulate solid particle impact erosion under controlled conditions by adjusting particle velocity, mass flow rate, impingement angle, and specimen orientation. It is suitable for standardized testing and comparative analysis of metals, ceramics, polymers, and coated surfaces.
Standards
You can conduct erosion tests in accordance with the following international standards:
(1) ASTM G76 – Standard Test Method for Conducting Erosion Tests by Solid Particle Impingement Using Gas Jets
(2) DIN 50332 – Erosion Testing by Particle Jet Method
(3) ISO 20567-1 – Paints and Varnishes – Determination of Stone-Chip Resistance – Part 1
(4) ISO 20567-2 – Paints and Varnishes – Determination of Stone-Chip Resistance – Part 2
