“…Laser Surface Strengthening Process. According to effect of laser surface strengthening process on high NiCr indefinite chilled iron roll material [1,2] , two kinds of laser surface strengthening processing parameters were optimized, and each kind performed laser surface strengthening process on the column surface of same sample group ten pieces φ45×12mm samples, to optimize the parameters(see Table 2). The metallographic examination results of laser surface strengthening samples were showed in Table 3 and Fig.…”

Rolling friction and abrasion test of high NiCr indefinite chilled iron roll material was developed on Arms Abrasion Tester made in Japan. The results showed that among two groups of samples with laser surface remelted-strengthening, C2 group samples of higher laser power and quicker linear speed had higher wear-resistance, and №6 sample of C2 group has the best with 1.5 mm beam diameter, 240-250W power and 30 mm/s linear speed, its total wear extent of three work conditions was only 16.3mg, and its wear-resistance increased 34.8% compared with №3 sample which had the best wear-resistance in C1 group without laser surface remelted-strengthening,; and for contrast of average wear-resistance of three work conditions, C2 group increased 49.3% compared with C1 group, it was showed that the effect of laser surface remelted-strengthening on high NiCr indefinite chilled iron roll material were very evident.
