摘要： The friction stir welding apparatus includes a pin (20) on which a soft nitrided layer (50) is formed. The soft nitrided layer (50) is formed of an iron lithium oxide layer (51) and a nitrided diffusion layer (52). The atom of the iron lithium oxide layer (51) penetrates into a space between atoms at the surface of the pin (20) to form the nitrided diffusion layer (52).

摘要： In a method of treating a nitrided/nitrocarburized workpiece, at least a portion of the workpiece is subjected to a first step in which at least one laser beam is moved in at least one pass over the portion, until the surface layer of the portion is transformed in part or in full, and until the distribution of the nitrogen concentration in the diffusion zone is modified. In a second step at least one laser beam is moved in at least one pass over said portion so as to enable the nitrogen concentration in the underlying diffusion layer to be reduced.

摘要： In a method of forming an oxide layer, ozone is generated by reacting an oxygen gas having a first flow rate with a nitrogen gas having a second flow rate of more than about 1% of the first flow rate. A reactant including the ozone and nitrogen is provided onto a silicon substrate. A surface of the silicon substrate is oxidized via the reaction of the reactant with silicon in the silicon substrate. The flow rate of the nitrogen gas is increased while ozone serving as an oxidant is formed by reacting the nitrogen gas with the oxygen gas. Thus, the oxide layer or a metal oxide layer including nitrogen may be rapidly formed on the substrate.
