Plating is a finishing process in which a metal is deposited on a surface. Plating has been done for hundreds of years; it is also critical for modern technology. Plating is used to decorate objects, for corrosion inhibition, to improve solderability, to harden, to improve wearability, to reduce friction, to improve paint adhesion, to alter conductivity, to improve IR reflectivity, for ...
Hot plate welding, referred to as fusion welding in many industries, is commonly used to join plastic pipes. These pipes, as opposed to steel ones, are less likely to rupture during an earthquake. [ 1 ]
Fusion welding is a generic term for welding processes that rely on melting to join materials of similar compositions and melting points. [1] Due to the high-temperature phase transitions inherent to these processes, a heat-affected zone is created in the material [ 1 ] : 755 (although some techniques, like beam welding , often minimize this ...
Sidewall fusion is typically employed in conjunction with either socket or butt fusion methods as a complementary process and many fusion machines designed for butt fusion are also equipped for sidewall fusion. Adaptor plates that match the outside diameter of the main pipe are applied to the heating plate to perform this type of fusion. [8]
After welding, a number of distinct regions can be identified in the weld area. The weld itself is called the fusion zone—more specifically, it is where the filler metal was laid during the welding process. The properties of the fusion zone depend primarily on the filler metal used, and its compatibility with the base materials.
Diffusion bonding involves no liquid fusion, and often no filler metal. No weight is added to the total, and the join tends to exhibit both the strength and temperature resistance of the base metal(s). The materials endure no, or very little, plastic deformation. Very little residual stress is introduced, and there is no contamination from the ...
The resin and hardener part together is known as the "Binder". As the name indicates, in Fusion bonded epoxy coatings the resin part is an "epoxy" type resin. “Epoxy” or “Oxirane” structure contains a three membered cyclic ring — one oxygen atom connected to two carbon atoms – in the resin molecule. This part is the most reactive ...
Direct bonding, or fusion bonding, is a wafer bonding process without any additional intermediate layers. It is based on chemical bonds between two surfaces of any material possible meeting numerous requirements. [ 1 ]
