Hot-dip aluminizing is a process in which aluminum steel undergoes hot-dip coating with alloys such as aluminum silicon alloy. This process guarantees that the metallurgical bond that exists between the aluminum coating and sheet of steel is strong enough.
Hot-dip aluminizing of low carbon steel was done in molten Al-7Si-2Cu bath at 690C for dipping time ranging from 300 to 2400 seconds. Characterization of the intermetallics layer was done by using scanning electron microscope with energy dispersive spectroscopy.
Aluminizing of Carbon Steel Dr. Abdullah Yusuf Majeed* Abstract This paper provides a mechanism to study aluminum diffusion microstructure, phase structure and different properties of the aluminized layer in carbon steel.

Hot dip aluminizing of low carbon steel is carried out in pure aluminium bath and Al-5wt% Cr bath. The coating is characterized by scanning electron microscopy and chemical composition of the coating is analysed by EDS (energy dispersive spectroscopy) attached to SEM.
A hot-dip aluminizing approach is proposed for fabricating an aluminum coating on the carbon steel surface. This aluminum coating is anodized to produce a ceramic oxide layer. The ceramic coating is identified as a mixture of -AlOOH, -AlOOH and -Al 2 O 3 .
Aluminizing is particularly effective for protecting mild, low alloy and high carbon steels. It is very effective at protecting generator chimneys, ducts, generator mufflers, and boiler chimneys against heat and corrosion at high temperatures. Spray aluminizing is particularly advantageous in marine and acidic environments.
Hot-dip aluminizing is a process in which with alloys such as aluminum silicon alloy aluminum steel undergoes hot-dip coating.This process make sure that the metallurgical bond that exists between the aluminum coating and sheet of steel is strong enough.This in turn, produces a substance with distinct property combinations neither possessed by aluminum or steel individually.Steel that has been aluminized can protect against temperatures as high as 800C and has better protection against , d carbon hot dip aluminizing steel
Aluminized Type 1 Carbon Steel Applications. Aluminized Steel Type 1 is continuously hot dip coated on both sides with an aluminum/silicon coating. The hot dip process, pioneered by AK Steel, provides a tight metallurgical bond between the steel and the coating.
Aluminized steel is steel that has been hot-dip coated on both sides with aluminium-silicon alloy. This process assures a tight metallurgical bond between the steel sheet and its aluminium coating, producing a material with a unique combination of properties possessed neither by steel nor by aluminium alone.
Aluminized Type 2 Carbon Steel Applications. Aluminized Type 2 steel was developed for superior environmental corrosion resistance and combines the strength of a steel substrate with the corrosion resistance of aluminum. It is produced by continuous hot dip coating of steel strip in a bath of molten, commercially pure aluminum.

A low carbon steel was hot-dip aluminized, and corroded in the N2/0.4%H2S-mixed gas at 650-850C for 20-50 h in order to find the effect of aluminizing on the high-temperature corrosion of the low carbon steel in the H2S environment.
A hot dip aluminizing process to simulate the continuous galvanizing line (CGL) was carried out in three successive steps by a hot dip simulator: the pre-treatment for removing scales on the 200 250 mm2 and 1mm in thickness cold rolled steel sheet, the dipping in 660C Al-Si melt for 3s and the cooling.
The development, prpcess, principle and characteristics of hot dip aluminizing technique are reviewed, and the microstructure and formation mechanism of Fe - Al intermetallics are analyzed. The effects of dipping temperature and time on the thickness of pure aluminum and the intermetallic layers are also discussed.
Aluminizing plain carbon steel or steel alloys increases their resistance to oxidation at high temperatures (773-1073K) and also increases the corrosion-resistance of steel in hydrocarbons and sulphurous atmospheres . There are several techniques that have been used to obtain a layer of aluminium over a steel surface on a commercial scale.
