The oxidation of an Fe(111) surface covered with carbon or nitrogen was studied using the AES method. The rate of oxidation depends on the form of the carbon or nitrogen. The oxidation rate of an iron surface precovered with an atomic non-metal or implanted with a non-metal is similar at the initial stage (θ O <1) to that of a clean iron surface. The oxidation process is inhibited by the...
The segregation of nitrogen, phosphorus, sulphur and carbon in iron causes the formation of Fe X X bonds on the surface. The system metal (Fe(111),Mo(100))-carbon has been studied using the AES method. The bonds Fe C observed for lower surface coverages were transformed to Fe C C bonds for higher coverages and the interaction between iron atoms and carbon atoms decreased. In the case of molybdenum...
