    • A process for treating a workpiece, said process comprising the steps of: (c) altering the temperature of a workpiece surface wherein at least one condition selected from the group of: thermal treatment rate, relative motion between the surface and said thermal treatment rate, coolant flow rate onto said surface, heating flow rate onto said surface and the relative speed between the heating means or the cooling means and the surface is controllable; (d) simultaneously measuring temperatures at a plurality of locations over the surface of the workpiece; (c) determining an average temperature of the temperatures measured in step (b); (d) comparing the average temperature to a preselected minimum temperature and a preselected maximum temperature for the workpiece; and (e) automatically adjusting at least one of the controllable conditions if said average temperature is not between the preselected minimum temperature and the preselected maximum temperature for the workpiece. A system for performing a thermal treatment process and the resulting product are also provided. Standard deviations of all temperature readings and controlling the relative motion speed between the thermal coating deposition head and the workpiece provide another improvement for obtaining temperature uniformity over the workpiece surface.
    • 1。一种用于处理工件的方法,所述方法包括以下步骤:(c)改变工件表面的温度,其中选自以下的至少一个条件:热处理速率,表面之间的相对运动和所述热处理速率, 在所述表面上的冷却剂流速,加热到所述表面上的流速和加热装置或冷却装置与表面之间的相对速度是可控制的; (d)同时测量工件表面上多个位置处的温度; (c)确定在步骤(b)中测量的温度的平均温度; (d)将平均温度与工件的预选最小温度和预选最大温度进行比较; (e)如果所述平均温度不在所述工件的预选最小温度和预选最大温度之间,则自动调节至少一个可控条件。 还提供了用于执行热处理工艺的系统和所得产品。 所有温度读数的标准偏差和控制热涂层沉积头与工件之间的相对运动速度为获得工件表面上的温度均匀性提供了另一个改进。
