摘要： A sliding element for internal combustion engines may include a ferrous base provided with a film applied upon a sliding surface. The film may have, sequentially, a metal connecting layer, a transitional layer, and a contact layer. The transitional layer may include a carbide containing a metal element. The contact layer may contain DLC (diamond-like carbon) doped with the metal element of the transitional layer, the DLC containing a maximum of 2% hydrogen by weight. An atomic ratio between metal and carbon in the contact layer in terms of a ratio Me/C is equal to or less than 0.1.

摘要： The present invention is related to a method of fabricating an aluminum matrix composite by a simple process of heating a mixture of a ceramic reinforcing phase and aluminum in nitrogen containing atmosphere and an aluminum matrix composite fabricated by the same. The aluminum matrix composite may be fabricated by heating to temperatures even lower than the melting temperature of aluminum as well as to temperatures higher. The exothermic nitridation reaction contributes to the melting of the aluminum matrix and the aluminum nitride formed in-situ as a result may act as an additional reinforcing phase.

摘要： A material that is useful as a wear-resistant member, a highly functional photocatalytic material, a photoelectric conversion element material, etc., is produced without the need for complicated processes or complicated handling, which are problems of the prior art. Provided is a method for producing a surface-treated metallic titanium material or titanium alloy material, the method comprising the steps of (1) forming titanium nitride on the surface of a metallic titanium material, and (2) heating the metallic titanium material with titanium nitride formed on the surface thereof obtained in step (1) in an oxidizing atmosphere. Also provided is a method for producing a surface-treated metallic titanium material or titanium alloy material, the method comprising, between steps (1) and (2) above, the step of anodizing the metallic titanium material with titanium nitride formed on the surface thereof obtained in step (1) in an electrolyte solution that does not have an etching effect on titanium, thereby forming a titanium oxide film. Further provided is a surface-treated material.

摘要： A surface treatment for a metal substrate includes a nitride layer and a diamond-like carbon coating on said nitride layer. The metal substrate can be a titanium-containing substrate. The nitride layer and diamond-like carbon coating serve to improve the tribological properties of the metal substrate.

摘要： Embodiments described herein generally relate to a processing chamber having one or more gas inlet ports located at a bottom of the processing chamber. Gas flowing into the processing chamber via the one or more gas inlet ports is directed along a lower side wall of the processing chamber by a plate located over each of the one or more gas inlet ports or by an angled opening of each of the one or more gas inlet ports. The one or more gas inlet ports and the plates may be located at one end of the processing chamber, and the gas flow is directed towards an exhaust port located at the opposite end of the processing chamber by the plates or the angled openings. Thus, more gas can be flowed into the processing chamber without dislodging particles from a lid of the processing chamber.

摘要： Provide a metal surface reforming method enabling metallic products with superior characteristics such as surface hardness, heat resistance, corrosion resistance, high temperature oxidation, high temperature corrosion, and environmental corrosion and the like.Halogenation treatment of heating and retaining a base material in an atmosphere containing a halogen based gas is performed on a base material of iron based metal or nickel based metal, then nitride processing of heating and retaining the halogenated base material described above in an atmosphere containing a nitrogen source gas is performed, then chromizing treatment is performed by placing the nitrided base material in a powder containing metal chromium powder to form a surface reformed layer on the base material described above. These metallic products obtained have high hardness, superior heat resistance and corrosion resistance, and exhibit superior performance in high temperature oxidation, high temperature corrosion, erosion, and cavitation and the like environments. Further, the metallic products described above exhibit superior performance in acid or alkali environments, neutral environments, and corrosive environments such as chlorides like salt water.

摘要： Disclosed are a method for adjusting the pore size of a porous metal material and the pore structure of a porous metal material. The method comprises: permeating at least one element into the surface of the pores of the material to generate a permeated layer on the surface of the pores, so that the average pore size of the porous material is reduced to within a certain range, thus obtaining a pore structure of the porous metal material having the pores distributed on the surface of the material and the permeated layer provided on the surface of the pores.

摘要： The invention relates to a method for making a thin finished product to be formed by deformation that combines strength with resistance to a highly corrosive environment. The method comprises forming a sheet of stainless steel with a microstructure consisting predominantly of ferrite, austenite, martensite or a mixture thereof, with a thickness of less than 3 mm, to a three dimensional semi finished product, treating said semi finished product with a nitrogen-containing atmosphere at a temperature of between 1000° C. and 1200° C. during a time and under a nitrogen pressure, sufficient to saturate the product through the thickness with a nitrogen content between a lower limit of 0.3 wt % and an upper limit that is provided by the beginning of nitride separation, cooling down said product at such a rate and nitrogen pressure that nitride separation is avoided, and subsequently machining the nitrogen saturated semi- finished product to the finished product. The invention further relates to a rotary shaving assembly prepared by the method of the invention.
