carbon steel with an aluminum coating
Aug 30, 2019 · 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 -Al2 O 3. The XRD analysis indicates that the ceramic coating is poorly crystalline.
This is because, in aluminized steel, the main structural component of the finished part is still plain carbon steel. The aluminum alloy coating is only 30 to 270 grams per square meter or 0.10 to 0.90 ounces per square foot of surface area. Most of the cost of aluminized steel goes into the operating expenses of the hot dipping process. Evaluation of Aluminum/Ceramic Coating on Fasteners to Feb 01, 1986 · These coatings are described and compared with zinc plated fasteners and other metals in a galvanic series. In environmental testing, stainless steel fasteners and carbon steel fasteners coated with zinc and aluminum-filled coatings, are coupled with aluminum, tin, copper, and 300 series stainless steel.
