Abstract
Disclosed herein are embodiments of alloys configured to form a coating with two contrasting physical behaviors: 1) reduced hardness with the end result of an easily machinable coating and 2) high abrasion resistance. Generally low hardness will result in low abrasion resistance. However, embodiments of the alloys described herein are able to maintain a low hardness while exhibiting higher abrasion resistance.
