Abstract
The present disclosure provides alloys for coating a steel substrate, the alloys comprising aluminum and one or more of zinc, magnesium, and zirconium. The alloy coatings have a percent total pore volume of about 5% or less and an average pore diameter about 10 microns or less. The present disclosure further provides methods of depositing aluminum alloy onto a substrate, magnetron sputtering targets, and methods for making coated steel.
