Printing recording head

Abstract

Abstract PURPOSE:To obtain the title head wherein the abrasion life of a contact electrode part is long and long-term printing recording is possible by forming the surface of the contact electrode part from a layer composed of a composite material consisting of a metal matrix material and fine ceramic particles. CONSTITUTION:A large number of recording electrodes are arranged on a substrate 1 patternwise in parallel and a layer composed of a composite material consisting of a metal matrix material and fine ceramic particles is provided to the exposed parts not covered with an insulating film 3 of each recording electrode 2 as a contact electrode part 4. As the metal matrix material, Ni or Co is designated and, as the fine ceramic particles, fine particles composed of Al2O3 or BN are designated and the average particle size thereof is pref. set to 0.3-30mum and the thickness of the layer is pref. set to 5-20mum. The ratio of the metal matrix material and the fine ceramic particles is pref. set so that the fine ceramic particles are contained in the layer composed of the composite material within a range of 2-37vol.% and said layer is formed by composite electroplating. As a result, the abrasion life of the contact electrode part becomes long and long-term printing recording becomes possible.
