Abstract
A railcar for transporting coal includes steel sheets metallized with an aluminum coating on the interior surfaces thereof normally engaged by coal lading. A coating thickness of substantially 0.006-0.009 inch significantly extends the service life of the railcar by inhibiting corrosion and abrasion of the steel sheets by the coal. The method includes the steps of cleaning all interior surfaces of the railcar sheets prior to a metallizing operation and followed by application of a seal coat.
