The external scale of cobalt sulfide and yttrium oxide-surfide particles in the inner scale were found respectively after corrasion in Pa .!$+ lo-'' Pa Q. Beneath the external scale, a region of internal sulfidation-oxidation of yttrium was also present. The comion pduct in lo-' Pa .!$+ 10-l5 Pa Q was only a very thin surface layer of yttrium oxysulfide and an internal oxidation zone of yttrium.
