Today a technique to enhance the characteristics of woven nickel wire mesh has been found called as sintering that is based on molecular diffusion bonding. It can also be followed again to combine several layers of mesh together to produce diverse and extremely useful group of permeable materials that was not known earlier in the engineering sector. Sintered wire mesh is designed with the diverse range of required mechanical characteristics, pore sizes and limited permeabilities and is significant in the various applications.

How Sintering is done?

Sintering is basically a thermal procedure that develops diffusion bonds across the tangent metal surfaces at their contact points without the inclusion of filler metal or bonding agent. An ideal condition of high temperature and isostatic pressure develops this type of bond through a combination of several mechanisms such as surface and volume molecular diffusion, evaporation and recondensation, grain development and recrystallization, deformation and plastic flow.

During perfect sintering, these techniques join to develop a protectively fused joint at every metal to metal contact point. This process is used to sinter together wires and fine screens to develop an extensive variety of materials and laminating these materials to coarser support structures like perforated metal, expanded metal or heavy structural wire meshes.

An essential factor is that in the entire conditions the melting point of alloy is not crossed while sintering and incipient melting is not allowed.

Need of Sintered wire mesh

Sintering is done on the several kinds of woven wire mesh. The key reason is to develop bond among all wires at the positions where they intersect hence preventing any motion among them. The woven meshes are normally sensitive to edge fray. Consider an inch2 of 100 mesh containing 200 wires connecting at 10,000 intersections, an exhaustive count to bonding is done at a specific moment by any other process. But by ideal sintering, every position is completely fused. In fact small discs can be punched then from the cloth without any movement. It is essential in several applications including filtration of aircraft hydraulic fluids, pharmaceutical filtration where loose wires may otherwise cause catastrophic damage. By sintering mesh shape becomes rigid and the wires do not move under specific pressure hence the aperture size becomes constant during operation.

Sintering is also known as heat processing. Under the controlled process atmosphere and cycle the wire mesh is delivered with shining and clean surface, extremely ductile and metallurgically solution annealed. Regardless of annealing, the total tensile strength is enhanced in the weaves generally because of wire bonding. Improved thermal and electrical conductivities are received. Increased forming and ductility properties are received with the strength to maintain the shapes.
