热双金属是一种控温材料,被广泛用作控温或报警器的关键元件。它对材料提出的要求是:1)两层金属要牢固结合;2)材料性能稳定,能在高温、低温或静态下长期使用。采用粉末轧制法结合热双金属有显著优点:通过复合界面上粉末间的分子扩散、互相溶解及成分过渡等,形成固溶过渡合金以改善二金属的结合性质及结合强度,从而提高材料稳定性及性能一致性,并增
Hot bimetal is a temperature control material that is widely used as a key component of temperature control or alarm. Its requirements on the material are: 1) the two layers of metal to be firmly bonded; 2) the material properties of stable, long-term use in high temperature, low temperature or static. Adopting the powder rolling method in combination with the hot bimetal has the obvious advantages that the solid solution transition alloy is formed through the molecular diffusion, mutual dissolution and composition transition between the powder at the composite interface so as to improve the bonding property and the bonding strength of the two metals so as to improve the material stability Consistency and performance, and increase
