AIR JET EROSION TEST RIG – TR 470 PURPOSE The Ducom TR 470 – Air Jet Erosion Tester is designed to evaluate resistance to erosion by air jet carrying erosive particles. DESCRIPTION The Ducom TR 470 is used to understand and characterize air jet erosion resistance of variety of materials like metals, ceramics, coatings, etc… Erodent of required characteristics carried by jet of air and impinged upon a simple under test. The velocity of particles, angle of impingement, flow rate and duration of the test are controlled. Facilities to conduct high temperature tests are also available (optional). The erosion resistance of samples is determined using the loss of weight method. APPLICATION 1. Metals 2. Ceramics 3. Coatings STANDARD ASTMG 76 FEATURES ? Measurement of particle velocity ? Airline filters of dust and moisture ? Adjustable angle of impingement ? Dust confinement system ? Variable abrasive feed rate ? High temperature tests(optional) SPECIFICATIONS PARAMETERS UNIT MIN MAX REMARKS Angle of incidence degree 15 90 In 15 degree steps.
