Use at high speed the coating of PVD super ZX of efficient treatment

Japan of Css" Type=text/css Rel=stylesheet> stays in company of friendly electrical engineering hard alloy to use the PVD coating technology of advanced accept rice technology and own development, developed successfully use at cutting cutting tool, mix by TiAlN of accept rice class AlCrN ultrathin coating is arranged alternately (amount to about 1000) the thick coating that combine and becomes -- PVD is super ZX coating. The physical sex visibility of this kind of new-style coating issues a list. With original coating (of TiN and AlN multilayer coating) photograph comparing, this kind of new coat raised aluminous content, realized function optimization: Coating hardness raised 40%(to raise 56GPa) from the 40GPa of original coating; Added chromium because coating is medium newly (Cr) , the beginning of coating oxidizes temperature raised about 200 ℃ (raise 1029 ℃ ) from the 816 ℃ of original coating. Hardness of coating of name coating construction (GPa) begins oxidation temperature (℃ ) remains presses stress (GPa) sound blasts off (AE) detects (TiN/AlN408160 of N) original coating.

The 7 formation according to coating mechanism, undertook optimizing adjustment to condition of besmear Fu craft, the remains that makes coating medium presses stress to be chased to coating appearance face from hard alloy matrix increase gradually, distributing into gradient. Its are as a result, fight without what damage coating not only flake function, and pressed stress on average to increase than original coating 1.

2GPa. As a result of the effect that coating of accept rice class overlaps alternately, those who restrained exterior crackle is patulous, improved coating intensity and wear-resisting performance thereby, raised point of a knife to fight the dependability of collapse blade considerably, make cutting tool life achieves the 2 times above of original coating cutting tool. It is treatment example below: (The ACK300 of super ZX coating that 1) uses at cast-iron milling uses gear case of FCD450 of milling of ACK300 coating cutting tool the effect of body. A large number of coating arose to flake after the coating cutting tool that uses other company machines 350, and after with ACK300 cutting tool of super ZX coating machines 400, the loss of bit is very slight still. (2) processes steel / stainless steel uses SCM435 of milling of ACP200 coating cutting tool with ACP200/ACP300 of super ZX coating steel when, the relation of cutting speed and cutting tool life. Experiment by contrast the result is knowable, below the requirement of high speed milling that exceeds 300m/min, wear-resisting function and fight the ACP200 with oxidation superior performance the 2 times above that the life of cutting tool of super ZX coating is original coating cutting tool, show preeminent treatment result. With ACP300 dynamo of treatment of cutting tool of super ZX coating uses bolt end panel (SUS316 stainless steel) result. The because of caustic of collapse of point of a knife disuse after the coating cutting tool of other company machines 30, and cutting tool of coating of ACP300 super ZX can machine 70, cutting tool life lengthened 1 times above. (The roller seating space that 3) turning small part uses cutting tool of coating of AC530U super ZX to machine gear with AC530U of super ZX coating (material is pulverous agglomeration alloy) example. After original cutting tool machines 60, because point of a knife has worn away big and disuse; And performance of wear-resisting of AC530U coating cutting tool is superior, after machining 90, wear away very small, final treatment number achieves 120, cutting tool life lengthened 1 times.
