Material response to particle impact during abrasive jet machining of alumina ceramics

Machining of novel alumina/cyanoacrylate green ceramic compacts

“…Solid particles can be removed by methods, such as ultrasonic machining, electrical discharge machining (EDM), laser beam machining (LBM), electro chemical machining (ECM) and abrasive jet machining (AJM) [8]. However, the main limitations to the use of these techniques are the high 0924 initial investment cost and restrictions on the types of material that can be machined [9].…”

Effect of Air-Abrasive Treatment on Oxide-Carbide Ceramic Object Operating Properties

“…A promising production process for manufacturing objects made of ceramic materials is jet-abrasive treatment, including action of a high-speed abrasive jet on a workpiece surface [1]. As a result of this action on a workpiece there is formation of a surface layer giving various ceramic materials improved properties [2].…”

Analysis of Oxide-Carbide Ceramic Surface Layer Stress-Strained State with Jet-Abrasive Treatment

“…This favorable effect is determined by the mechanism of ceramic surface layer dispersion under action of a stream of abrasive particles, exhibiting high energy and not connected by strong bonds between them [3,4]. In performing JAT for ceramic components with the optimum regime a surface is formed with a low degree of defectiveness compared with that after diamond grinding; manifold reduction in number of cracks, chips, and areas of local breakdown in a surface layer [5,6].…”
