Hot-dip Galvanization – a process of coating fabricated steel
Hot-dip galvanizing (HDG) is the process of coating fabricated steel by immersing it in a bath of molten zinc. It is a form of galvanization.…
Polyvinyl Alcohol (Properties, Uses)
The water-soluble synthetic polymer is polyvinyl alcohol (PVA), also known as PVOH or PVAL, which has the idealized formula (CH2CH(OH)n. It works well for film…
Sendzimir Process – a surface coating process
The Sendzimir process is a surface coating process where the workpiece is dipped into a bath of zinc and aluminum to form a surface. This…
Metal Fume Fever
Inhalational exposure to metal-containing fumes generated by welding and related processes may result in the development of the clinical syndrome known as “metal fume fever.”…
Embrittlement – a process of material becoming brittle due to loss of ductility
Embrittlement is the process of a material becoming brittle due to a loss of ductility. It is a significant decrease of the ductility of a…
Rack Plating – a method used to electroplate brittle and complex parts
Rack plating is a method used to electroplate brittle, large, and complex parts that are difficult to plate using other processes. It is the preferred…
Liquid Metal Embrittlement
Liquid metal embrittlement (LME) is a phenomenon where metals that are usually ductile become prone to brittle intergranular failure after exposure to certain liquid metals.…
Chemical Milling – a subtractive machining process
Chemical milling is the subtractive machining process using baths of temperature-regulated etching chemicals to remove material for producing the required shape. It is also known…
Electroetching – a metal etching process
Electroetching is a simple metal etching process. It is a metal etching process that involves the use of a solution of an electrolyte, an anode,…
Cadmium plating – a type of coating process
Cadmium plating is under scrutiny because of the environmental toxicity of the cadmium metal. It is a type of coating process that offers technical benefits…
Electroplating – a process of applying a metal coating on another piece of metal
Electroplating is the process of applying a metal coating on another piece of metal (or another conductive surface) through an electro-deposition process. It is a…
