Galvanization or galvanisation (or galvanizing as it is most commonly called in that industry) is the process of applying a protective zinc coating to steel or iron, to prevent rusting.
Electrotyping
Electrotyping (also galvanoplasty) is a chemical method for forming metal parts that exactly reproduce a model.
Dew point
Dew point is the highest temperature at which airborne water vapor will condense to form liquid dew.
Passivation (chemistry)
Passivation, in physical chemistry and engineering, refers to a material becoming "passive," that is, less affected or corroded by the environment of future use.
Anodizing
Anodizing (also spelled anodising, particularly in the UK, India and Australia) is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts.
Chromate conversion coating
Chromate conversion coating is a type of conversion coating used to passivate steel, aluminum, zinc, cadmium, copper, silver, magnesium, and tin alloys.
Spray painting
Spray painting is a painting technique where a device sprays a coating (paint, ink, varnish, etc.) through the air onto a surface.
Corrosion
Corrosion is a natural process, which converts a refined metal to a more stable form, such as its oxide, hydroxide, or sulfide.
Electroplating
Electroplating is a process that uses electric current to reduce dissolved metal cations so that they form a coherent metal coating on an electrode.
Thermal spraying
Thermal spraying techniques are coating processes in which melted (or heated) materials are sprayed onto a surface.
Chrome plating
Chrome plating (less commonly chromium plating), often referred to simply as chrome, is a technique of electroplating a thin layer of chromium onto a metal or plastic object.
