g112

Note : 100 Series China National Highways spread out from Beijing ( exception : G112 , a ring road around Beijing ) .

注：100系列中国家公路蔓延，从北京（例外：G112，一个在北京二环路）。

As a result based on all the above investigates , the synthetical effects of adding nickel-wrapped WC or single crystal WC to G112 is better than that of cast WC .

综合以上三种WC对覆层各方面不同的影响，作为镍基合金激光熔覆层中的强化相，镍包WC和单晶WC综合作用效果优于铸造WC。
