AIR JET EROSION TESTER

A Solid Particle Erosion (SPE) Tester that is capable of conducting erosions tests across a very wide range of erosion conditions.

The Ducom Air Jet Erosion Tester is a unique and a feature rich erosion tester that is capable of testing bulk materials and coatings under erosion. Its capabilities range from subjecting sample to tightly controlled gentle erosion to some of the harshest erosion conditions seen on the field.

Product Features
ADJUSTABLE IMPINGEMENT ANGLE
Solid particle erosion tests use fine particles as a test consumable. The Ducom Air Jet Erosion Tester is a fully self contained setup that minimizes particle escape. It has a sealed hopper for storing particles before the test. It also has a built in particle collector, complete with a filter to minimize particles escaping into the air. 

 

TEMPERATURE CONTROL
Product Feature Snapshot Here

A dust preventive chamber with a hot air exhaust system ensure safe working conditions. The pneumatic control system ensures automatic open and closure of the heat furnace. Sufficient insulation prevent direct exposure to high temperature. 

PARTICLE FLOW CONTROL

Particle flow rate is controlled by a motor, gear head and belt assembly connected to below a hopper. High flow rate of particles up to 300 g/min can be achieved by using a high-speed motor.

The furnace is used to heat the samples and the air carrying the particles is heated by a joule heating technique. A maximum temperature of 1200 °C (specimens and air carrying the particles) can be achieved.
