Inasmuch as the changes of the surface roughness of the fire-damaged parts have affected the accuracy and the frictional performance of the machine, we studied the formation of the oxide film and the changes of the surface roughness of the fire-damaged machine elements. As explained in the preceding reports, the accuracy of the fire-damaged machine is severely influenced by the fire conditions, especially by its temperatures. For practical purpose, it is most convenient to measure the surface hardness in order to judge this condition. In this paper, we studied this hardness problem. The micrograph of the metals damaged by the fire was also investigated.
