          熱等靜壓擴散連接

          通過熱等靜壓技術可以使兩種及兩種以上的同質或異質材料通過擴散焊接作用連接在一起,連接方式包括固體-粉末、固體-固體的擴散焊接。尤其在相互焊接的各種材料間性能差異較大或者界面比較復雜時具有其他焊接方式無法比擬的優勢。

          HIP擴散連接是在密閉的容器中,在原子快速移動的高溫下施加壓力,從而使緊密接觸的表面在固態下連接到一起的焊接工藝。HIP可以連接兩種不同的材料,如金屬-金屬、金屬-非金屬、非金屬-非金屬,根據兩種材料熱力學性能的差別考慮是否添加過渡層元素。從材料形態上來講可以是粉-固、固-固、粉-粉連接。

          HIP diffusion bonding is a welding process, that, in a closed container, pressure is applied under the high temperature, so that the surface will be bonded together. HIP can connect two different materials, such as metal-metal, metal-nonmetal, nonmetal-nonmetal; whether transition layers are needed or not depends on the thermodynamics properties of the two (or more) materials. The bonding types can be powder-solid, solid-solid and powder-powder.

           

          l  連接相同性能材料時,由于界面不產生液相,界面結合強度與母材相當;

          l  連接不同性能材料時界面可實現良好的冶金結合,且性能不低于兩種材料中的較低者。

          l  可以連接接觸面具有復雜形狀的零件,并實現嚴格的尺寸控制;

          l  可在一道工序中連接多個同類或異類材料;

          l  可使常規焊接方法無法連接的脆性金屬實現固態連接;

          l  由于作用在零件上的等靜壓力高且均勻因此減少及消除了在連接區外側的微小氣孔。

          l  For bonding of materials with the same properties, because the liquid phase is not exist at the interface, the interfacial bonding strength is equal to that of the base metal;

          l  Materials with different properties can achieve perfect metallurgical bonding, and the performance of the composite is no less than the lower of the two.

          l  Able to bond parts with irregular contact surface and realize the strict size control.

          l  Able to bond more than two kinds of similar or dissimilar materials in one process;

          l  Able to realize the solid connection of brittle metals that cannot be connected by the conventional welding method;

          l  Because of the high isostatic pressure, the small pores outside the joint district are reduced or eliminated.
