MATERIAL WITH ANTIBACTERIAL CHARACTERISTICS AND MARINE LIFE RESISTANCE

摘要

PURPOSE: To produce a material stably and continuously having antibacterial characteristics in the field related to living and marine life resistance in the industrial field and also being industrially valuable in respect of mechanical properties, workability, corrosion resistance, and price by specifying the composition of a copper-iron-aluminum alloy. ;CONSTITUTION: An alloy has a composition consisting of, by weight ratio, 10-80% iron, 1-10% aluminum, and the balance copper with inevitable impurities. It is preferable that 1-15% of one element among chromium, nickel, manganese, and silver is further added according to uses. This alloy can be worked, an a solid material, in this state into a plate or wire and used and also can be thermally sprayed onto the surface of a material having no antibacterial characteristic to provide antibacterial characteristic. At this time, a wire for thermal spraying material can be produced by ordinary wire drawing and a powder can be produced by gas atomizing, water atomizing, etc. Moreover, this alloy is applicable also to the ornamental field because it can change its color, according to its composition, from gold to reddish brown, yellow, etc.;COPYRIGHT: (C)1996,JPO
