Title:
POWDER FOR THERMAL SPRAYING AND PROCESS FOR FORMATION OF SPRAYED COATING
Document Type and Number:
WIPO Patent Application WO/2012/002475
Kind Code:
A1
Abstract:
A powder for thermal spraying, which consists of granulated-sintered cermet particles that contain a metal having an indentation hardness of 500 to 5000N/mm2. The granulated-sintered cermet particles have a mean diameter of 30μm or less, while the primary particles in the granulated-sintered cermet particles have a mean diameter of 6μm or less. The granulated-sintered cermet particles exhibit a compressive strength of 100 to 600MPa. It is preferable that the metal contained in the granulated-sintered cermet particles comprises at least one selected from the group consisting of cobalt, nickel, iron, aluminum, copper, and silver. The powder is usable in low-temperature thermal spraying processes such as cold spraying using nitrogen as the operating gas.
