Abstract

PROBLEM TO BE SOLVED: To readily form a metal surface layer on the surface of a substrate without internal insertion and fixation by forming a metallic layer on the surface of the substrate by a gas deposition method. SOLUTION: A ceramic member 1 having a metallic surface layer has a metallic layer 3 on the surface of a substrate 2. In a gas deposition method, the substrate 2 is set in front of a nozzle of a delivery pipe. A carrier gas is sent to a raw material tank, passed together with a metallic raw material in the raw material tank through the delivery pipe, jetted from the nozzle and collided against the surface of the substrate 2. The metallic raw material collided against the surface of the substrate 2 forms a dense film on the surface of the substrate 2 by low-temperature sintering. Consequently precision machining for securing fit tolerance of a ceramic substrate for the internal insertion and fixation of a metal member is not required. The ceramic member 1 having the readily weldable metallic layer 3 can be formed by using a weldable metal such as stainless steel, etc., as the metallic layer 3.

In the above prior art, a metal member having an inner diameter within a fitting tolerance range with respect to the outer diameter of the ceramic capillary is required for the inner fitting and fixing. This fitting tolerance is required to be as small as possible in order to shorten the processing time of the outer diameter after the inner fitting is fixed, but there is a limit to the inner diameter processing of the metal member. Conventional methods for fitting and fixing a ceramic capillary to a metal member include press-fitting and bonding. However, press-fitting involves problems such as deformation of the metal member and insufficient fixing force. However, there is a problem that the position of the ceramic capillary is shifted. Therefore, the present invention has been made to solve the above-mentioned problems, and a ceramic member having a metal surface layer capable of easily forming a metal surface layer on a substrate surface without being internally fixed, and a method of manufacturing the same. The purpose is to provide.
