#In the form of abrasive jet it is used for machining like cutting drilling and engraving of brittle materials. Surface fast cleaning and preparation are done by using abrasive jet for welding and plasma spray coatings. The erosion tests of turbine blades propellers are done by using abrasive jet application.
#The abrasive water jet process utilizes an ultrahigh pressure intensifier pump that pressurizes water up to 55 000 psi (3 800 bar) forcing it through a small nozzle typically inch ( mm) in diameter. This generates a highvelocity water jet stream at speeds of up to 3 000 feet per second (914 m/ sec).
#Applications of abrasive jet machining (AJM) Work surface cleaning Although sand blasting or grit blasting is economical for this purpose abrasive jet machining (AJM) can also be applied if tight quality of finished surface is desired. AJM can be advantageously used for cleaning metallic or ceramic surfaces (substrate must be hard).
#The highspeed jet of abrasive particles can be ground and polished under tight control. (2) Compared with the conventional polishing technique its "machining tool" is liquid and there is no problem of abrasive wear. The removal function remains constant and the surface accuracy is easy to control.
