Zinc thermal diffusion coating can be done by following the patented Greenkote process.
The coating formed on the zinc granules when zinc reacts with ferrous sulfate is black in color. It is due to the formation of ferrous sulfide as a result of the reaction.

Before coating steel with zinc, ensure proper surface preparation by cleaning and degreasing the steel to remove any contaminants. Check the humidity and temperature conditions to ensure optimal curing of the zinc coating. Use proper protective gear such as masks and gloves to avoid inhalation or skin contact with zinc during the coating process.
The zinc coating no longer protects the underlying metal from rusting, once water and air gets through the crack.
Yes it does.
Heat is needed because if you just placed copper with zinc, you'd just have a zinc coating around the copper. The composition of zinc and the composition of zinc will be separate instead of becoming one solution. The heat allows the two to bond, allowing the zinc and copper to move around, and become an alloy (a solid solution) - brass.
"Galvanized" is an adjective used to describe steel which has been coated with zinc metal. Galvanized steel is quite well protected from corrosion by the zinc coating which provides the steel with both physical and chemical protection. There are currently 3 processes which are used for galvanizing steel: (1) hot dip galvanizing, (2) electrogalvanizing, and (3) thermal diffusion galvanizing.

Zinc is the coating on the steel that makes it galvanized.
Galvanising is the process of application of zinc coating on steel surfaces. It prevents steel surface from rusting.

Check the humidity and temperature conditions to ensure optimal curing of the zinc coating. Use proper protective gear such as masks and gloves to avoid inhalation or skin contact with zinc during the coating process.
Sheradising is a method of coating a metal, usually steel, with zinc. The zinc is transferred from a vapour phase.
Yes, zinc has a higher thermal conductivity than glass. Zinc has a thermal conductivity of about 116 W/m·K whereas glass typically has a thermal conductivity ranging from 0.8 to 1.4 W/m·K. This means that zinc is much more effective at conducting heat compared to glass.
the unit is : g/m2

A zinc nail is a nail that has been coated or plated with zinc. This is done to prevent the metal from corroding or rusting when exposed to moisture or humid environments. Zinc coating helps preserve the nail's integrity and prolong its lifespan.
