Detailed description of the invention
This utility model is described in detail by specific embodiment and Fig. 1 to Fig. 3 below in conjunction with the application.
A kind of PCB cutter with multifunctional composite coating, is made up of with the wolfram steel blade 2 with cutting function the handle of a knife 1 for clamping, and described wolfram steel blade is arranged at the front end of handle of a knife, and this PCB cutter can be milling cutter or drill bit.
The surface of described wolfram steel blade 2 is provided with transition zone 3, and this transition zone 3 is zirconium (Zr) transition zone, titanium (Ti) transition zone or chromium (Cr) transition zone, and the thickness of this transition zone 3 is 100-500nm.Its role is to improve the adhesive force of coating, especially as wolfram steel and the middle-class between the superhard film on its upper strata, play a part relax internal stress and increase adhesive force.
The surface of described transition zone 3 is provided with superhard film 4, this superhard film 4 is zirconium aluminum carbon nitrogen (ZrAlCN) superhard film, zirconium silicon-carbon nitrogen (ZrSiCN) superhard film, titanium aluminum carbon nitrogen (TiAlCN) superhard film, titanium silicon-carbon nitrogen (TiSiCN) superhard film, chromium aluminum carbon nitrogen (CrAlCN) superhard film or chrome-silicon carbon nitrogen (CrSiCN) superhard film, and the thickness of this superhard film 4 is 200-1500nm.Above-mentioned superhard film effect is to strengthen the blade of PCB cutter, it is as the superhard film of four elements, owing to the incorporation of third and fourth element makes the lattice on microcosmic material structure change, therefore than general conventional Was Used hardened layer such as ZrN (zirconium nitride), TiN (titanium nitride), CrN (chromium nitride) etc., there is higher hardness.
The surface of described superhard film is provided with oxidation resistant layer 5, this oxidation resistant layer 5 is zirconia-alumina (ZrAlO) oxidation resistant layer, zirconium silicon oxide (ZrSiO) oxidation resistant layer, titanium oxide aluminum (TiAlO) oxidation resistant layer, titanium oxide silicon (TiSiO) oxidation resistant layer, chromium oxide aluminum (CrAlO) oxidation resistant layer or oxidation chrome-silicon (CrSiO) oxidation resistant layer, and the thickness of this oxidation resistant layer (5) is 100-800nm.This oxidation resistant layer has high temperature oxidation stability to protect the blade of PCB cutter, and it is the oxide layer utilizing coating process to be initially formed densification, and further oxidation reaction when therefore can slow down or avoid machining has higher heatproof character.
As it is shown in figure 1, coat successively on the surface of the wolfram steel blade 2 of PCB cutter: transition zone 3, superhard film 4 and oxidation resistant layer 5.
In the specific embodiment one shown in Fig. 2, it is provided that PCB cutter be a milling cutter, it has wolfram steel handle of a knife 1 and a wolfram steel blade 2.This milling cutter is removed surface and oil contaminant with ultrasound in advance, dry the moisture being attached on this milling cutter again, in the way of cathodic arc deposition (cathodic arc deposition), carry out the coating of edge of milling cutter face coat, be followed successively by: thickness is the transition zone Zr of 500 nanometers；Thickness is the superhard film ZrAlCN of 1000 nanometers, and vickers (Vicker ' s, the 10g) hardness of this superhard film is Hv4200；Thickness is oxidation resistant layer ZrAlO of 500 nanometers.The working durability of milling cutter is 8 times without coating milling cutter in this embodiment.
