Abstract: A stainless steel that includes chromium and other alloying element as a plurality of alloying elements including: a base material layer including chromium of a specified chromium content necessary for forming a passive film or more; and a superficial layer including chromium at a lower chromium content than the chromium content contained in the base material layer, and the superficial layer including the other alloying elements at a same content of the other alloying element as the content of the other alloying element contained in the base material layer.

Abstract: A PCVD apparatus includes a waveguide member which supports the workpiece with a portion of the waveguide member positioned in a reactor and causes microwaves output from a high-frequency output device to propagate to the workpiece. In a process of gradually increasing an intensity of the microwaves propagating to the workpiece through the waveguide member from “0”, the intensity of the microwaves output from the high-frequency output device when step-up of a bias current of the workpiece occurs is referred to as a first intensity, and in a process of gradually increasing the intensity of the microwaves from the first intensity, the intensity of the microwaves when step-up of the bias current occurs again is referred to as a second intensity. During film formation, the microwaves having an intensity of higher than the first intensity and lower than the second intensity are output from the high-frequency output device.

Abstract: There is provided a surface treatment method in which a processing gas is brought in contact with a heated processing object made of steel, an element in the processing gas is solid-solutionized, and thus a surface treatment is performed on the processing object. The processing object is heated to a heating temperature in a vicinity of a processing temperature at which the surface treatment is performed by heating an atmosphere in which the processing object is disposed. The surface treatment is performed by bringing the processing gas in contact with a surface of the processing object while the processing object which is heated is directly heated to the processing temperature.
