A coating of a thermally hardened alloy of nickel and a nickel-phosphorus compound covers the internal face portions of a spinning pot which are engaged by the fibrous material being spun. The alloy produced from an electroless nickel plating solution is rolled to improve surface smoothness and density, and the rolled coating is heat treated to precipitate a portion of the phosphorus present in the form of a finely dispersed nickel-phosphorus compound. Silicon carbide may be dispersed in the coating to further increase its hardness.
