A consumable part for a plasma processing chamber, comprising:

• a plasma facing side of the consumable part;
• an engineered surface formed into the plasma facing side of the consumable part;
• a plurality of raised features defining the engineered surface, wherein features of the plurality of raised features are arranged in a predefined pattern, wherein each of the plurality of raised features includes a top region having an outer edge and a sidewall;
• and
• a base surface of the engineered surface that surrounds the each of the plurality of raised features, such that a corresponding sidewall of a corresponding raised feature extends up at an angle from the base surface to a corresponding top region,
• wherein the consumable part is configured to be installed in the plasma processing chamber,
• wherein the consumable part is configured to be exposed to a plasma and byproducts of the plasma.
