摘要： The invention aims to provide a hard film which is improved in high-temperature corrosion resistance without impairing high sliding characteristics (wear resistance, low frictional coefficient) inherent in a titanium nitride thin film and which is suitable for a slide member such as a bearing or a seal used in rotary machines operated at a high temperature, such as a steam turbine and a gas turbine. For attaining this aim, the invention provides a Cr-containing titanium nitride film which is composed of a nitride containing Ti and Cr as main components, the crystal particles thereof having a face-centered cubic crystal structure, and the crystal thereof being highly oriented toward (200) face.

摘要： A coating material has a first layer deposited on a base material and a second layer deposited on the first layer. The first layer is made of a Ni-base alloy or a Co-base alloy containing carbon as an unavoidable impurity. The second layer is made of a hard material containing carbide and a metal component. The first layer serves as a barrier for preventing carbon from being diffused from the second layer into the base material to prevent the base material from being carburized.

摘要： An object to be analyzed for corrosion and corrosion prevention is divided into a plurality of adjacent regions of plural types by a dividing plane, with one of the adjacent regions being referred to as an attentional region with a boundary as the dividing plane and the other as a non-attentional region with a boundary as the dividing plane. An initial current density or an initial potential is imparted to each element of the boundary of the non-attentional region to effect a boundary element analysis for determining a relationship between a potential and a current density in each the element. A potential distribution and a current density distribution in the attentional region in its entirety are determined, using the relationship between the potential and the current density in each the element of the boundary of the non-attentional region as a boundary condition for the attentional region.

摘要： Austenitic cast iron has excellent corrosion resisting properties and has been preferentially used in machines or machine parts intended for handling corrosive fluids such as seawater. Cases, however, have been reported of machines or machine parts made of austenitic cast iron failing after they had been put to prolonged service at relatively low temperatures. The present inventors have located stress corrosion cracking at the cause of this failure.In accordance with the present invention, methods of using salt water resisting machines or machine parts made of austenitic cast iron that has graphite in the form of spheroids or nodules and which comprises by weight %: C.ltoreq.3.0, Si=1.0-3.0, Mn.ltoreq.1.5, P.ltoreq.0.08, Ni>24-28%, Cr.ltoreq.5.5 and the balance being Fe to minimize stress corrosion are provided.
