对迄今为止世界各国公认的热双金属和复合材料的最先进的生产方法——室温固相结合法进行了试验。室温固相结合法包括结合面清理、“核结合的形成”、扩散退火(烧结)三部份。双金属组元通过不同热处理制度使组元机械性能相接近,组元通过酸洗槽或碱槽进行脱脂处理,用100目砂轮或1400转/分的钢丝刷制造“新生金属面”。将两组元或多组元的“新生金属面”重叠,在轧制力为200吨的φ200/φ460×570四辊冷轧机上,控制轧制速度为3～8m/min。以压下率为68-72%进行轧制,使“新生金属面”呈一体地破碎,结合面上不同组元之间的金属原子达到原子间距,形成结合核心。以熔点最低的组元的0.5-0.7倍熔点进行烧结。使结合核心长大成面结合。
So far, the world’s most recognized thermal bimetallic composites and the most advanced production methods - room temperature solid phase bonding method was tested. Room temperature solid phase binding method includes the combination of surface cleaning, “the formation of nuclear binding”, diffusion annealing (sintering) three parts. The bimetallic components are brought close to the mechanical properties of the components by different heat treatment systems. The components are degreased by a pickling or caustic bath and the “nascent metal surface” is manufactured with a 100 mesh grinding wheel or a 1400 rpm wire brush. The two or more components of the “new metal surface” overlap in the rolling force of 200 tons of φ200 / φ460 × 570 four-roll cold rolling mill, the control of the rolling speed of 3 ~ 8m / min. Rolling at a rolling reduction of 68-72% causes the “new metal surface” to be broken in one piece, and the atomic distance between the metal atoms in different components of the surface is reached to form a combined core. The lowest melting point component of 0.5-0.7 times the melting point sintering. The combination of core growth into a surface.
