Abstract

PURPOSE:To provide the titled hammer having a deep hardened layer, hardly generating abrasion and seizure and having a reduced wt., obtained by a method wherein a specific metal is deposited on the printing surface of a hammer comprising a titanium alloy and a surface hardened layer comprising an intermetallic compound with titanium is formed by heat diffusion. CONSTITUTION:On the printing surface of a hammer for a line printer constituted by a titanium alloy, at least one metal among Fe, Cr, Si, Sn and Co is deposited. As a depositing method, a sputtering, a vapor deposition or a plating methods are used. In the next step, a surface hardened layer comprising an intermetallic compound of said metal and titanium is formed by heat diffusion. The hardened layer with a thickness of about 150mum can be formed.
