    摘要: A chromium plating method using a plating bath comprising trivalent chromium and an electrode which is an anode comprising an electrode substrate of titanium, tantalum, zirconium, niobium or an alloy thereof, coated with an electrode catalyst comprising at least iridium oxide and, optionally, at least one of titanium, tantalum, niobium, zirconium, tin, antimony, ruthenium, platinum, cobalt, molybdenum, tungsten or an oxide thereof. The anode may be placed directly in the chromium plating bath or may be placed in an anode chamber partitioned from the chromium plating bath with an ion-exchange membrane. The chromium plating method may be a barrel plating method.

    摘要: A titanium composite material is disclosed which comprises a titanium or titanium alloy substrate, a base layer formed thereon of a calcium phosphate compound resulting from calcination of a hydrochloric or nitric acid aqueous solution of the calcium phosphate compound, and a covering layer thereon of a calcium phosphate compound formed by sintering a suspension of the calcium phosphate compound applied to the base layer. The composite material is useful as a biological implant. It is produced by activating the surface of the substrate, forming the base layer by calcining the solution coated on the substrate and then forming the covering layer by sintering the suspension coated on the base layer. The covering layer may be hydrothermally treated to increase its crystallinity.
