The present work investigates the compressive property of Al matrix composite foams at different temperatures between room temperature and 200 ◦C. Elevated temperature results in a decreased compressive strength and energy absorption capacity of as-received Al foams. Therefore, to maintain the compressive property, the Al2O3 ceramic coating was deposited on the Al struts of the foams by the pla...
