Title: Production of hard film-coated member
Inventor: OGINO TOSHIHIKO
IPC: C23C16/30
Filed: 1992-04-27
Abstract: PURPOSE:To sufficiently bring about the characteristic of a hard film at the time of forming two kinds of hard films by vapor growth by forming a first hard film and then specifying the atmosphere in a reaction furnace until the temp. is controlled to the temp. at which a second hard film is formed. CONSTITUTION:The furnace is heated to an optimum temp. T1 to form a first hard film, and a gaseous reactant is introduced. The first hard film is formed before and after the reaction furnace temp. reaches T1, and the state is kept for a specified time. The supply of the first gaseous reactant is stopped after the first hard film is formed, and the furnace temp. is decreased from T1 to the optimum temp. T2 to form a second hard film. At this time, gaseous hydrogen or an inert gas is introduced into the furnace. Immediately before or after the furnace temp. reaches T2, a second hard film forming gaseous reactant is introduced into the furnace to form a second hard film, then the supply of the second gaseous reactant is stopped, and the furnace temp. is decreased. The formation of an intermediate layer, in which the first and second hard films are intermixed, is prevented in this way.
