| titleOfInvention | METHOD OF VOLUME RELAXATION AND STRENGTHENING OF THE SURFACE OF METAL DETAILS IN THERMOACOUSTIC - TAO METHOD OR JOINT THERMOACOUSTIC AND CHEMICAL TREATMENT - METHOD OF TACHO IN THE CASE OF TREATMENT |
| abstract | 1. The method of processing metal parts when exposed to a stream of compressed air on the parts placed in the chamber, characterized in that in order to ensure volume relaxation and hardening of the surface of the parts in the chamber, the conditions of acoustic resonance exposure in the range of 500-5000 Hz by recirculating the air flow with an air blower capacity from 10 to 100 m / min at elevated pressure in the range of 1.5-4.5 atm, and additional conditions are created for thermal exposure by direct heating of parts in a chamber from 150 to 450 C ° or cooling them by air flow. 2. The method according to claim 1, characterized in that for the implementation of joint thermoacoustic and chemical processing of products in the chamber under conditions of acoustic resonant exposure, conditions are additionally created for surface chemical exposure by introducing gaseous chemicals, such as methane, hydrogen, nitrogen and ammonia, as well as their mixtures into the air flow, while the concentration of gas components relative to the air in the chamber is: for hydrogen: from 2 to 2.5%, for methane: from 10 to 25%, for nitrogen: from 15 to 25%, ammonia: from 15 to 45%. 3. The device carrying out the work according to the method of claim 1, made in the form of a hermetically sealed cylindrical chamber, with a lifting lid, in the center of which is a centrifugal air blower, axial resonator chambers are placed inside the chamber in which the products to be processed are placed, the resonator chambers also have devices for heating parts in in the form of electric heaters, rotary shutters of the slot nozzle for adjusting the entrance width |
