Title:
【発明の名称】ディスインテグレータ装置を使用して被覆された粒子を製造する方法
Document Type and Number:
Japanese Patent JPH07502785
Kind Code:
A
Abstract:
A metal-coated particle is prepared by providing a disintegrator apparatus with a working chamber containing counter-rotating disks equipped with teeth design to accelerate particles towards one another, providing a first material and a second metal as powders, such that the first material is harder than the second metal and introducing the first material and second metal powders into the working chamber of the disintegrator apparatus, whereby the soft second metal collides with the hard material and is coated onto the surface of the hard first material. A metal-coated metal with an intermetallic interface is prepared by introducing a first material and a second metal as powders into a disintegrator working chamber containing counter-rotating disks and teeth designed to accelerate particles towards one another. The first material harder than the second metal and is capable of reacting with the second metal to form an intermetallic compound. The disks of the disintegrator are counter-rotted so as to cause the metal powders to collide with each other, whereby the hard metal powder is mechanically coated by second metal. The rate of rotation of the counter-rotating disks are further increased in a high velocity process whereby high local temperatures generated on impact cause a reaction to occur at the first material/second metal interface to form an intermetallic compound.
