PURPOSE:To obtain a traveler which exhibits excellent performance in high- speed spinning by forming a hard composite nickel layer in which pulverized hard particles exist as an eutectoid material and a nickel alloy as a matrix on the surface of the traveler consisting of a hard steel wire. CONSTITUTION:The traveler of a required shape such as horizontal type or vertical type is formed by using the hard steel wire or alloy steel wire as a stock. The hard composite plating layer in which about 0.2-3mu pulverized hard particles exist as the eutectoid material and the nickel alloy contg. nickel and phosphorus as the matrix is formed on the surface of such traveler to about 5-15mu thickness. The traveler is then subjected to a heat treatment for about 50-150min at about 350-450 deg.C to crystallize the nickel alloy and to intensify the adhesiveness between the pulverized hard particles and the matrix. A nickel-phosphorus alloy, nickel-tungsten-phosphorus alloy, etc., are used for the nickel alloy and silicon carbide, tungsten carbide, etc., are used for the pulverized hard particles. The traveler for the spinning machine which has the high hardness and improved wear resistance is thus obtd. |
