摘要： PURPOSE:To enhance the corrosion resistance, and extend the life of a sodium- sulfur battery by using an iron alloy containing given amounts of chromium and silicon for a positive-active-material case, a positive-collector material and the like which touch a positive active material. CONSTITUTION:A positive-active-material case 5 which serves as both a positive terminal and a collector material, is prepared from a Fe alloy containing 12-35wt% of Cr and 1.2-10wt% of Si. If it is desired, at least the surface of the former case 5 that touches a positive active material is coated with the former Fe alloy. The former alloy, which has a good workability, has an enhanced corrosion resistance to high-temperature Na2S3 that is a reaction product, and thereby the life of the battery can be increased.

摘要： PURPOSE:To enhance anti-corrosion characteristic by providing a particular alloy layer sprayed at a low pressure to the surface of basic material. CONSTITUTION:A layer consisting of Cr, Cr-Fe or TiN sprayed at a low pressure is formed on the surface of basis material. The plasma is generated by supplying Argon gas into the arc 27 form the operation gas supply device 17 and a voltage is also applied across a nozzle 8 and a cooling base material 25. Thereby, the plasma jet 29 is sprayed toward the surface of cooling base material from the nozzle 8. Under this condition, the power of a raw material of the jar is supplied to the nozzle 8 from the supply hole 9. Particles of powder of jar material sprayed into the nozzle 8 becomes fine melted drops by the heat of plasma and it is accumulated on the surface of cooling base material 25 and the accumulated drops are condensed and thereby a cylindrical mold 31 is formed at the surface of cooling base material. Since the cathode jar is formed by plasma spraying within a low pressure ambience, comparatively economical material having excellent anti-corrosion characteristic can be used.

摘要： PURPOSE:To form a film having superior heat resistance, corrosion resistance and wear resistance by reacting an alloy contg. a specified amount of one or more among Cr, Ti, Nb, Ta and W with a reactive gas in the gas by a reaction exciting means to form a film contg. a compound of said element. CONSTITUTION:An alloy contg. 0.1-40% one or more among Cr, Ti, Nb, Ta and W is reacted with a reactive gas in the gas by a reaction exciting means such as heating to form a film contg. a compound of said element on the surface of the alloy. The base of the alloy is Fe, Ni, Co or the like. CCl4, CH4 or the like is used as the reactive gas when carbide is formed as the compound, N2, NH3 or the like is used when nitride is formed, N2, H2 and a very small amount of H2O, O2 or the like are used when oxide is formed, and BCl3 or the like is used when boride is formed. The desired deposited film is efficiently obtd. on the surface of the alloy.

摘要： PURPOSE: To obtain a stainless steel material with superior rust resistance, by treating stainless steel with an aqueous soln. of an Si compound and by sbjecting it to bright annealing.
CONSTITUTION: Stainless steel or a stainless steel strip is treated with an aqueous soln. of an inorg. silicate such as sodium orthosilicate or an aqueous suspension of silica sol. to stick the silicon compound to the surface of the steel material. The treated steel material is subjected to bright annealing in a prescribed atmosphere, and it is cooled to form an Si oxide film on the surface. By this method a stainless steel material with superior surface luster and rust resistance is obtd.
