Abstract:It was found that rare earth influenced per process of permeation layer forming, and that the tooth of layer was thinner, thicker, straighter and longer by observing permeation layers at different holding times.It was so image, lifelike and audio-visual by computer kinetic simulation that the layer forming could be continuously observed. Because it con forms to reality, the computer kinetic simulation can forecast the layer thickness and it will offer a reasonable permeating technology.
Key words: rare earth; B-Al; permeability; computer simulation
