Abstract
PURPOSE: To smoothly slide a valve and improve its water and abrasion resistance by a method wherein the sliding surface of a valve guide is composed of ceramics and a valve stem is coated by metal spraying with Ni-WC-Co base alloy or WC-Co base alloy.
CONSTITUTION: A valve 1' is opened through a rocker arm 5 in accordance with the rotation of a camshaft 7. A valve guide is composed of ceramics. The surface of the stem part 13 of the valve 1' is coated by metal spraying with wear-resistant composite material of Ni-WC-Co base alloy, WC-Co base alloy or the like. As a result, the valve can be opened smoothly and closed without being applied with lubricating oil thereto and moreover its wear and abrasion resistance are increased.
