Definition – What does Metallizing mean?
Metallizing is a process which involves depositing a thin metallic film on the surface of non-metallic objects.
The most common processes of metalization include:
- Galvanic metallization
- Thermal metal spraying
- Fire metallization
- Diffusion metallization
- Vacuum metallization
- Contact metallization
Corrosionpedia explains Metallizing
Metallizing is a very common coating process which is used to improve the resistance of a material against corrosion, wear and fatigue. The metallization process is applied in many industries, such as:
- Oil and Gas
- Solar Product Manufacturing
Thermal spray processes are often referred to as metallizing. Metals like zinc, aluminium, silver, etc. are used to deposit in the form of a metallic film on the base material such as plastic, glass or metal to prevent corrosion of base material.
Metallizing consists of three steps:
- 1. The base material is prepared by abrasive blasting, metal spraying, etc. to ensure adhesion of the sprayed metal.
2. A heat source is used to create molten particles of coating material, then an atomizer sprays this molten material onto the substrate.
3. Upon contact, the particles flatten onto the surface, freeze and mechanically bond, firstly onto the roughened substrate and then onto each other as the coating thickness is increased. Once applied the surface can be worked for a smoother surface painted.
The metal used for deposition may be either in the form of wire or powder. When the coating material is used in powder form it is known as powder metallizing. When it is in wire form the process is called wire metallizing. Coating thickness may vary from .004″ to thicker coats in the range of .012″ – .014″.
Samples of pure zinc metallisation carried out by MSB
This pure zinc coating can be used for any steel body shells, chassis work. Once applied any type of colour coating can be applied. offering outstanding corrosion protection.
When left unpainted this coating will last over 20 years exposed to all weathers. So if you are looking for ultimate anti corrosion protection then you have found it. From replacement car panels to full steel body shells. See the link above showing a Land Rover Chassis being coated and other vehicle projects we have undertaken in the past.
Metallisation of a Land Rover Chassis
This is the next best thing to galvanised dipping without the worry of frame distortion or build up of materials in the box sections or any mounting threads.
Once complete it can be wet painted or powder coated.
Hardwood metallation. Light blast work to raise the grain,then coated in pure copper or aluminium. Hard wearing & outstanding. Can be overcoated with clear lacquer. Other pure metal finishes available. Can be used for flooring, window frames, furniture, artwork infact any type of soft or hardwood. For samples please call.
Oversized Bearing Housings
Here is a little trick for oversized bearing housings, This part is an alloy casting and the bearing were a very poor fit. We put our metallistion gun to work and sprayed a pure alloy metal on the surface to build up the walls. This item is now in the engineering shop being milled out to size
