n: a closed pressure vessel that has a furnace equipped to bum coal. oil. or gas and that is used to generate steam from water.

heat-treating process where carbon is introduced into a solid iron alloy by heating above transformation temperature range while in contact with a carbonaceous material (solid, liquid, or gas form of carbon). Usually quenched to produce a hardened outer s

cracking of a metal under combined action of tensile stress and corrosion in the presence of chlorides and an electrolyte (NACE). Starts at a pit, scratch or notch. Crack proceeds primarily along grain boundaries. The cracking process is accelerated by ch

n: a carbonaceous, rocklike material that forms from the remains of plants that were subjected to biochemical processes, intense pressure, and high temperatures. It is used as fuel.

n: The solid fuel. Used as SCM, manufactured by different coal stone.

sedimentary rock, often highly naturally fractured, composed of thermally modified plant remains.

n: any material that forms a continuous film over a metal surface to prevent corrosion damage.

a liquid, liquefiable, or mastic composition that, after application to a surface, is converted into a solid protective, decorative or functional adherent film (NACE).

n: a chemical substance that minimises or prevents corrosion in metal equipment.

a chemical substance or combination of substances that, when present in the environment, prevents or reduces corrosion (NACE).
