Die by surface modification to improve the life of

Conducted with a laser microscope is not powder coated vanadium-rich alloy tool steel stamping die after the semi-blanking 40500. Yam punch face and die on the side of the results of the determination of shape wear. In the end there is a big punch wear + This depression of deep cold treatment and EDC coated steel SKDI1 same situation. Figure 8 SKDIl for around 6 in the elbow and EDC bare cold case. After blanking 62,000 for semi-finished products by the first face of the concept of wear scratch the powder coating field 7 to the rich vanadium tool steel in the red most Taijin 405 (30 semi-core after the punch-side wear Rong Jiang Jing-like figure is not the powder B rich vanadium alloy tool steel, semi-finished pieces in the blanking 405O0 ah touch the surface after the wear shape (continued on page lI) 2 Weimei Hong et al: A new A1 sj corrosion Taijin a № a composition, melting and heat treatment. 1I white,[link widoczny dla zalogowanych], only a little darker, indicating that the new alloy can be seen only a very slight corrosion of the corrosion resistance of the new alloy is stronger than ZL30I, and its resistance to stress corrosion (s0c) performance can be very strong [. 6 Conclusion 1) through the use of added cover agent, in addition to gas refining, boric acid powder mixed in the red sand and increase in the vent of the melting method, can produce excellent corrosion resistance of new alloys. 2) a new alloy AI-Mg2 Si2 to solution treatment (520 ± 5 ℃ ,6-12h is appropriate. 3) The new alloy AI-M & A is better than the corrosion resistance of Si2 ZL301.

(Continued from page 8) shows. Noting the negative film side also had a large depression wear. That this is because the waste is not bound by blanking, waste several times due to the strong grazed the side of negative mode. This also means that a lot of wear and tear factor is the slip and the lateral force, product, or from the front of the latest cutting edge areas. The maximum friction work. Wear the most. 3 Conclusion Die cutting with orientation silicon steel sheet,[link widoczny dla zalogowanych], the order SKD1l, powder high speed steel, powder-rich vanadium alloy tool steel for the mold material,[link widoczny dla zalogowanych], through the use of diamond-like carbon coating (PVD.DLC.Me.DLC) and the EDM surface processing (EDc) of surface modification,[link widoczny dla zalogowanych], and application of deep-ling treatment, research aimed at environmental protection, as no lubrication drying mode blanking die life, the following conclusions: 1) Without surface modification, the order powder rich vanadium alloy tool steel mold longest. 2) by the Me-DLC coating SKDI1 and EDM surface. Die life can be raised by 2 times. 3) If the conduct of SKD11 cryogenic treatment can improve the die life of about l times. 4) If the deep cold treatment on SKD11 and EDM surface. Likely to die life increased about 8 times. 5) produced by powder method is not appropriate for EDM tool steel mold surface treatment, this treatment can actually reduce life expectancy.
