Welding technology research titanium plates and stainless steel mesh diffusion

Diffusion welding titanium plates and stainless steel Medical titanium bar‍ mesh using solid phase diffusion welding technology. In solid phase diffusion bonding is lower than the melting temperature of the substrate by a certain pressure, so that the material surface contact each other to achieve the local plastic deformation of close contact and the diffusion of atoms through the surface layer

And bonding to form a metallurgical connection process. This method does not cause macroscopic deformation of parts, melting or relative movement. Available with or without the proliferation of auxiliary material (ie, interlayer material) between + two mating surfaces. Diffusion bonding process can be divided into three phases: the first phase is in physical contact; The second stage is the atomic interdiffusion between titanium bar stock‍ the contact interface to form a strong bonding layer; volume of the third stage is gradually formed in the contact portion in the direction of the bonding layer development, creating a reliable diffusion welding titanium plate and welded joints of stainless steel mesh, taking into account the welding materials and propellant compatibility, combined with the ease of titanium and stainless steel plates welded mesh actual production, should try to avoid using diffusion auxiliary materials, namely by direct diffusion titanium alloy plate‍ welding technology of titanium plates and stainless steel mesh.
