Manual metal arc coatings, because the presence of δ-ferrite, exhibit significantly lower hardness, pitting corrosion resistance, and wear resistance than friction surfaced coatings. 4. Friction surfaced coatings in alloy 410 show comparable wear and corrosion resistance to alloy 410 bulk material in hardened and tempered condition.
Improved wear resistance of laser composite surfaced samples were attributed to a lower co-efficient of friction and an improved hardness.
