在同种材料或异种材料的接合中,经常使用粘接剂。而对于金属之间的接合,则采取焊接或钎焊.这种方法的接合借助于2个同种或异种材料熔融状态。所谓扩散结合,是用在纤维增强型和金属包层复合材料等制法上的方法,基本上是事先把对象金属加热到其熔点以下, In the bonding of the same kind of material or different kinds of materials, an adhesive is often used. In the case of joining between metals, welding or brazing is adopted, and the bonding of this method takes place by means of melting of two homogeneous or dissimilar materials. The so-called diffusion bonding is used in fiber-reinforced and metal cladding composite materials and other methods of production methods, is basically prior to the target metal heated to below its melting point,
