Air Jet Erosion Tester
The Air Jet Erosion Tester is a controlled gas-driven erosion testing system designed to evaluate the erosion resistance of materials and coatings under repeated particle impact. By accelerating abrasive particles using a high-velocity gas stream and exposing specimens to controlled temperature conditions up to 900 °C, the tester simulates realistic erosion environments. With closed-loop temperature control, adjustable impact angles, and precise particle velocity measurement, the system enables accurate and repeatable erosion performance evaluation across a wide range of applications.
Application
The Air Jet Erosion Tester is used to assess erosion behavior by exposing materials to abrasive particles of varying size, shape, temperature, and impact velocity.
Typical application scenarios and tested products include:
Aerospace materials and coatings: erosion and wear resistance evaluation
Metallic materials: gas-borne particle erosion performance
Polymer materials: erosion resistance under particle impact
High-temperature coatings: durability under thermal and erosive environments
Structural materials subjected to particulate flow conditions
Standards
The Air Jet Erosion Tester complies with internationally recognized erosion testing standards, including:
(1) ASTM G76 – Standard Test Method for Conducting Erosion Tests by Solid Particle Impingement Using Gas Jets
(2) ASTM G211 – Standard Test Method for Conducting Elevated Temperature Erosion Tests by Solid Particle Impingement Using Gas Jets
