I am drawing a blank, what are the colors associated with Oxidation during the different phases of iron sintering. I remember the colors are Blue, Matte, Gray, Straw, and frosted but I cant remember the phases or causes for each color.
Hardness will be the driving influence to abrasion resistance, especially dealing with a softer material such as wood causing the abrasive. Another factor you might consider will be the corosive resistance of the material. The moisture from wood can oxidize and weaken your material.
