The application provides a baffle assembly and a chemical vapor deposition system. The baffle assembly comprises: at least two baffle groups, which are respectively arranged in at least two temperature different filling areas of a vertical furnace; each baffle group comprises at least one baffle; the thicknesses of baffles in different baffle groups are different; the higher the temperature of the filling area where the baffle group is located, the smaller the thickness of the baffle in the baffle group. The application can make the sum of the thicknesses of the baffles and the films on the baffles in different baffle groups closer in the same reaction time, which is beneficial to reducing the thickness difference of the baffles in different baffle groups, and then the thickness monitoring step of the baffles can be synchronized, the replacement time and the cleaning time of different filling areas can be synchronized, and the efficiency of the thickness monitoring, replacement and cleaning of the baffles is improved. The edge part of the application is thinner than the middle part, the application has a convex structure, the adhesion of the baffle and the deposit can be reduced, and the baffle is convenient to take out.

The double-cavity multi-element alloy reaction tank comprises rotary shaft one and rotary shaft two arranged at the left and right ends of the tank body respectively, a transmission gear arranged on the rotary shaft two and matched with a driving unit, and a cover body covering the opening of the tank cavity of the tank body. A central flow channel extending in the vertical direction and transverse to the length direction of the tank cavity is formed at the central position of the width direction of the tank cavity. Hot air sent into the central flow channel can heat the material in the tank cavity at least at the central position of the width direction of the tank cavity. The present application can change the heat conduction path of a large reaction tank with a large width, can realize the purpose of simultaneously heating the material in the tank cavity at multiple positions in the width direction, can improve the heating speed, and can improve the consistency of the temperature in the tank body.

This invention belongs to the field of powder metallurgy component surface strengthening technology, aiming to solve the problem that existing clutch tooth surface strengthening processes struggle to simultaneously achieve geometric accuracy, wear resistance, and process efficiency. This invention provides a method for strengthening the wear resistance of clutch tooth surfaces, comprising: mixing iron-nickel-molybdenum alloy powder, nano-tungsten carbide powder, nano-alumina powder, and lubricant; adding a binder and melting and mixing; then adding the mixture into a mold for injection molding; subsequently performing solvent degreasing and thermal degreasing treatments; followed by pre-sintering treatment; then transferring the pre-sintered part into a chemical vapor deposition reaction chamber, where an intermetallic compound transition layer, a titanium carbide main layer, and a nanocrystalline surface layer are sequentially deposited on the tooth surface; then performing vacuum sintering, liquid phase sintering, and pressurized cooling; finally, subjecting the sintered part to hot isostatic pressing (HIP) strengthening treatment; and finally, grinding the tooth surface. This invention can simultaneously address the three aspects of clutch tooth surface strengthening processes: geometric accuracy, wear resistance, and process efficiency.
