Abstract
The invention discloses a stainless steel and ceramic composite material. The stainless steel and ceramic composite material comprises a ceramic layer, a buffer layer and a 304 stainless steel layer, wherein the ceramic layer is made from compound system ceramic prepared by firing barium oxide 32%, zirconium oxide 55% and boron oxide 13% by weight, and the buffer layer is one of a Nb metal layer and a Mo metal layer. The ceramic layer, the buffer layer and the 304 stainless steel layer are sequentially superposed and are fused into a whole through induction heating. The composite material has the excellent mechanical properties of 304 stainless steel and the characteristics of a ceramic material, and the stainless steel and ceramic composite material is combined tightly and has good shock resistance performance.
Description
technical field [0001] The invention relates to a composite material of stainless steel and ceramics, in particular to a composite material composed of ceramics, pure metal and 304 stainless steel. Background technique [0002] Stainless steel and ceramic materials are two kinds of materials that are widely used in industry and life. Stainless steel materials have good acid and alkali corrosion resistance, tensile, bending resistance, impact resistance and other mechanical properties, while ceramic materials have high hardness and good wear resistance. Due to their different properties, the two materials are often used in different fields. In recent years, many scholars are studying the combination of stainless steel and ceramic materials to form new composite materials, so that it has both the advantages of stainless steel and the characteristics of ceramic materials. [0003] In the Chinese patent titled "Connection Method of Stainless Steel and Alumina Ceramics and the C...
