| titleOfInvention | Multi-gas co-permeation strengthening system and process thereof |
| abstract | The invention discloses a multi-gas co-permeation strengthening system and a process thereof, belongs to the technical field of workpiece heat treatment, solves the problems of poor environmental protection, poor permeation effect and single permeation layer of the traditional heat treatment, and comprises a feeding unit, a ventilation unit, a heating pre-permeation unit, a multi-gas co-permeation strengthening unit, a cooling protection unit and a discharging unit which are sequentially connected. The invention replaces the traditional acid corrosion prevention process by the matching of all units, improves the environmental protection property, utilizes the ventilation unit, avoids air participation, improves the sufficiency of polyatomic penetration, combines the heating up pre-infiltration unit with microwave radiation, changes the surface tissue structure of the lamp post, accelerates the penetration speed and the depth of subsequent nitrogen element, sulfur element and chromium element, adopts the nitriding treatment in the ammonia atmosphere and then adopts the permeation promoting ball B to release gaseous carbon-sulfur-chromium complex compound during the multi-element gas co-infiltration strengthening treatment, realizes the carburizing, sulfurization and chromizing co-infiltration treatment, realizes the compound diversification of the infiltrated layer tissue, and improves the surface hardness of the lamp post. |
