Magnesium oxide single crystals were coated with copper, cobalt, nickel, aluminum, iron, and gold to determine what effect, if any, altering the surface would have on the mechanical strength of the MgO. The coated crystals were given various heat treatments to allow a metal oxide to form on the MgO surface. The specimens were bent, using a three‐point loading machine to determine the flow stress. These geld strengths were then compared. It was found that the iron, nickel, and cobalt oxide layers decidedly lowered the yield strength whereas aluminum, gold, and copper had no effect.
