APPARATUS FOR DETONATION COATING

摘要

Apparatus for the detonation coating of the surfaces of parts, which includes a detonation chamber (1) connected to a powder supply system (4) and a gas mixture supply system (3). A control system incorporates a powder detector (32) adapted to determine the amount of powder in the detonation products and connected with a control unit (22) through a feed-back circuit (33) which includes a coating thickness measuring unit (35) arranged to de- energize the apparatus after the predetermined thickness of the coating being applied is attained. The unit (35) has an A to D converter (37) and an adder (38) which stores the cumulative value from the detector (32) for successive detonations. When the adder (38) has a value substantially identical to a reference value stored by unit (36) the coating process is halted.
