    摘要： Provided is a novel high-nitrogen stainless-steel pipe which is not obtained with any conventional technique, the stainless-steel pipe having high strength, high ductility, and excellent corrosion and heat resistance and being obtained through size reduction of crystal grains and strengthening by slight plastic working besides formation of a gradient structure in which the concentration of solid-solution nitrogen continuously decreases gradually from the surface. Also provided are hollow materials of various shapes and sizes which are formed from the steel pipe and processes for producing the steel pipe and the hollow materials. An austenitic stainless-steel pipe is treated in a range of the temperatures not higher than the critical temperature for crystal grain enlargement of the steel pipe material to cause nitrogen (N) to be absorbed into the surface of the pipe and diffused into the solid phase, while minimizing the enlargement of crystal grains during the treatment. Thus, a gradient structure is formed, the structure including a part that is close to the surface part of the pipe and has been highly strengthened by the formation of a high-concentration solid solution of N and a part in which ductility gradually increases toward around the center of the cross-section of the pipe as the N concentration decreases. Thereafter, the pipe is subjected to size reduction of crystal grains by utilizing, for example, eutectoid transformation of the austenite phase, thereby greatly improving the elongation (ductility) of the steel pipe. Furthermore, the steel pipe is strengthened by slight plastic working to give a high-nitrogen austenitic stainless-steel pipe having high strength, high ductility, and excellent corrosion and heat resistance. A plurality of the thus-obtained high-nitrogen austenitic stainless steel pipes of the same quality are disposed one over another so as to result in dimensions, e.g., diameter and wall thickness, according to the use or strength level, and this pipe arrangement is united by adhesion processing through hot drawing, hot rolling, or other method to give a high-nitrogen austenitic stainless-steel pipe or hollow material which has high strength, high ductility, and heat resistance and has repetitions of the gradient structure within the wall. This stainless-steel pipe or hollow material can have large or small sizes and be of various kinds, and examples thereof include a hollow material for use as a container for storing high-pressure hydrogen gas which is for fuel cell vehicles (FCVs) and which does not suffer hydrogen gas embrittlement (HGE) in the presence of high-pressure hydrogen gas.

    摘要： A base member made of a metal in which aluminum is included, ceramics in which an aluminum element is included, or a composition member constructed by a metal in which aluminum and ceramics are included, is provided in a container in which a solid fluorine compound such as NaHF2 is filled. Then, the container is heated at a temperature higher than a decomposition temperature of the solid fluorine compound. After that, the base member is subjected to a heat treatment with the decomposed gas of the solid fluorine compound to form a fluoride layer on a surface of the base member. In this manner, it is possible to obtain an anti-corrosion member which shows a high corrosion property with respect to the corrosion gas of halogen series and its plasma, particularly with respect to chlorine gas and its plasma.

    摘要： Embodiments of the present invention are directed to an in-line system and process for forming a selective emitter solar cell. In one embodiment, a liquid dopant material is applied to a silicon substrate and dried to at least a semi-solid state. In another embodiment, a dopant material is deposited on a silicon substrate using a chemical vapor deposition process. A laser is then used to thermally excite regions of the substrate to drive the dopant atoms from the dopant material deep into the substrate to form highly doped regions. The substrate is then thermally processed to form a lightly doped emitter region and a shallow p-n junction in the remaining field region of the substrate. Conductive contacts are then deposited on the highly doped regions.

    摘要： A method of surface hardening a substrate made of an inorganic material by diffusing a different inorganic material into the substrate is disclosed wherein the diffusion is effected in an alkali metal gas atmosphere. The substrate may be made of titanium, zirconium, iron, yttrium, tungsten, tantalum or a material containing one of those elements as a principle component. The diffusion material may be boron, silicon or a material containing one of those elements. The alkali metal gas atmosphere is produced by heating metallic sodium, potassium, lithium or a combination thereof. The surface hardened substrate produced according to the method exhibits an increased Young's modulus of elasticity, hardness and mechanical strength and is particularly suitable in the manufacture of electro-acoustic diaphragms as well as other light weight, high mechanical strength articles.

    摘要： The laser nitriding method of making phosphor bronze with surface-embedded titanium carbide particles involves coating a cleaned phosphor bronze workpiece with a thin film formed of a carbonaceous layer mixed with nanosize particles of titanium carbide. The titanium carbide forms about 5 wt % of the thin film, and the phosphor bronze workpiece is composed of about 6.0 wt % tin, about 0.1 wt % phosphorous, and about 93.9 wt % copper. A laser beam is then scanned over the thin film formed on the phosphor bronze workpiece. Coaxially and simultaneously with the laser beam, a stream of nitrogen gas is sprayed on the thin film formed on the phosphor bronze workpiece in order to provide the workpiece with a nitride coating having nanoparticles of titanium carbide embedded therein.
