System of surgical staple cartridges comprising absorbable staples

A staple cartridge, comprising:

• a deck;
• an elongate slot;
• staple cavities defined in said deck;
• and
• staples positioned in said staple cavities, wherein said staples are configured to be deployed into a tissue environment, wherein said staples are comprised of a zinc-based alloy, and wherein said zinc-based alloy is selected such that said staples bio-corrode in said tissue environment within a predetermined bio-corrosion timeframe,
• wherein said staples comprise a coating, the coating configured to tune a rate of bio-corrosion of the staples to meet the predetermined bio-corrosion timeframe based on a mechanism of action, by balancing an increase of the rate of bio-corrosion caused by the zinc-based alloy and a decrease of the rate of bio-corrosion caused by a calcification.
