摘要

The present invention provides a titanium sheet covered with a protective film superior in high temperature oxidation resistance and high temperature salt damage resistance and a method of production of the same and an automobile exhaust system using the same. The titanium sheet covered with a protective film is formed on its surface with a protective film of a thickness of 1 to 100 μm where flake-shaped metal Al with an average thickness of 0.1 to 5 μm and average width or average length of 1 to 50 μm or grain-shaped metal Al with an average size of 0.1 to 30 μm is dispersed in 20 to 60 mass % silicone resin or silicone grease and comprised of Si: 15 to 55 mass % and C: 10 to 45 mass % and having a balance of unavoidable impurities. Preferably the titanium sheet of the substrate contains one or both of 0.5 to 2.1 mass % of Cu and 0.4 to 2.5 mass % of Al. The method of production is to brush or spray the above composition of a silicone resin on a titanium sheet to form a protective film and heat it at 150 to 300° C. for 5 to 60 minutes.
