WN nano composite structure small diameter knife coating and preparation method thereof |
| abstract |
A W-N nano composite structure small-diameter knife coating and a preparation method thereof relate to the field of material surface processing, and the composition of the coating is 80-100 at.% of tungsten and 0-20 at.% of nitrogen according to atomic percentage. The preparation method firstly ultrasonically cleans the small-diameter knife of the cemented carbide, and then plasma-etches the surface by the arc-enhanced glow discharge technology; and the N 2 and Ar are introduced into the cavity, and the negative bias and deposition temperature of the substrate are performed. Under the conditions of sputtering target power, magnetron sputtering coating is performed to obtain W-N nano composite structure coating. The invention adopts the magnetron sputtering technology to coat the substrate and deposit the W-N nano composite structure coating. The coating is well combined with the tool base, and the surface hardness of the small diameter knife is high, the chip removal performance is good, and the tool can be effectively improved. Service life and processing quality. |
