Abstract:
A method for plating films on a transmission mechanism includes the steps of: cleaning the transmission mechanism; injecting hydrogen and tetra-methylsilane gases and applying an electric current to generate a bias electric field within a working chamber, thereby forming an adherent film on the transmission mechanism; injecting hydrocarbon gas together with the hydrogen and tetra-methylsilane gases into the working chamber, thereby forming a mixed film on the adherent film; and injecting the hydrogen and tetra-methylsilane gases together with hydrocarbon gas into the working chamber while maintaining the bias electric field at 400-700 V and the applied electric current at 800-1500 watt, thereby forming a noncrystalline DLC film on the mixed film.
Abstract:
A method for film-coating drill bits comprises the steps of: providing a core drill bit; cleaning and further heating the core drill bit; forming an adherent film on the core drill bit; forming a mixing film on the adherent film; and forming a non-crystalline diamond-like film on the mixing film. The finish film-coated drill bit comprises an inner adherence film, a middle mixing film and an outer non-crystalline diamond-like carbon (DLC) film. The mixing film is composed of a non-crystalline diamond-like material and compositions of the adherence film. In the mixing film, the composition of the non-crystalline diamond-like material is higher in a position close to the DLC film.
Abstract:
A method for sintering anhydrous calcium sulfate material as biomedical material, includes the steps of: (a) preparing the anhydrous calcium sulfate material; (b) mixing the anhydrous calcium sulfate material with a sintering-support agent thoroughly to obtain a mixture waited for sintering; (c) die-pressing the mixture into a predetermined shape; and (d) executing a heat treatment onto the mixture to make the mixture be sintered to form the biomedical material having the predetermined shape.
Abstract:
A method for plating film on a heat dissipation module includes the steps of: cleaning the heat dissipation module; injecting hydrogen and tetra-methylsilane gases and applying an electric current to generate a bias electric field within a working chamber, thereby plating an adherent film on the heat dissipation module; injecting hydrocarbon gas together with the hydrogen and tetra-methylisilane gases into the working chamber, thereby plating a mixed film on the adherent film; and injecting the hydrogen and tetra-methylisilane gases together with hydrocarbon gas into the working chamber, thereby plating a noncrystalline DLC film on the mixed film.
