Title:
TITANIUM PLATE AND PROCESS FOR PRODUCING TITANIUM PLATE
Document Type and Number:
WIPO Patent Application WO/2010/140571
Kind Code:
A1
Abstract:
Provided are a titanium plate which has satisfactory seizing resistance and crack resistance, whereby the plate exhibits excellent press formability, and a process for producing the titanium plate. The titanium plate (10) comprises a titanium base (1) and a hard layer (2) partly formed on the surface thereof. The hard layer (2) has been formed so that when the surface of the titanium plate (10) is viewed through an examination image bearing a plurality of squares (M) in which each side of each square (M) has a length (W) of 10 µm, then the average of all dimensions of the hard layer (2) that are measured along the lines (S) constituting the squares (M) and crossing the surface of the hard layer (2) is 5-200 µm per mm2 of the surface of the titanium plate (10). The process for producing the titanium plate (10) comprises a hard-layer formation step in which a hard layer (2) is formed on the surface of a titanium base (1) and a hard-layer removal step in which the hard layer (2) is partly removed.
