【Abstract】 This report briefly introduces the analysis of Mn,Cr,V,W,Ti,Nb,Co,Zr,Ni,Mo,S,P,Si and Cu in alloy tool steel with X ray florescence spectrometer.After being polished with grinding whell and being cleaned with ethly alcohol,the test samples can be directly measured,and the results agree well with the standard values of the laboratory standards.The precision of the method (RSD) is in the range of 0 13%-9 56% ( n =8) for all elements except W,Ti,Nb and Zr.The method can be applied to many kinds of steel,such as chrome vanadium steel,manganese steel,die steel,middle low alloy steel,tool steel.The measure instrument should be rectified with two or three standard samples which the quantity contained is suitable.The standard samples include 1Cr18Ni9Ti,C17Ni2,25CrMo1V,30CrMnSiA,3CrW8V,Gx 8,Cr12MoV,chrome vanadium steel,manganese boron steel,middle low alloy steel and other kinds of steel.If there is not conditions to make work curves for all kinds steel separately,sometimes we don′t know what kind of steel for one complex sample,the more real way will be to make an overall work curves which contains more kinds of steel as far as possible.更多还原
