    Abstract: Method of laser hardening of a surface area of a workpiece, such as a surface of a journal of a crankshaft, comprising: generating a relative movement between the surface of the workpiece and a laser source to allow a laser spot to subsequently be projected onto different portions of said surface area, and during said relative movement, repetitively scanning the laser beam (2) so as to produce a two-dimensional equivalent effective laser spot (5) on said surface area. The energy distribution of the effective laser spot is adapted so that it is different in a more heat sensitive subarea, such as in an area adjacent to an oil lubrication opening, than in a less heat sensitive subarea, so as to prevent overheating of said more heat sensitive subarea.

    Abstract: A method of heat treating a workpiece, the method including projecting a laser beam from a laser source onto said workpiece, so as to produce a laser spot on said workpiece; projecting the laser spot onto different portions of said workpiece; and while projecting the laser spot, repetitively scanning the laser beam in two dimensions so as to produce a two-dimensional equivalent effective laser spot on said workpiece and thereby temper, reduce hardness of, enhance ductility of, and/or reduce brittleness of at least one of the different portions of the workpiece.

    Abstract: Ein Verfahren zum Laserhärten eines Oberflächenbereichs eines Werkstücks, wie etwa eine Oberfläche eines Zapfens einer Kurbelwelle, umfasst: Erzeugen einer Relativbewegung zwischen der Oberfläche des Werkstücks und einer Laserquelle, um einem Laserspot zu erlauben, nacheinander auf unterschiedliche Teile des Oberflächenbereichs projiziert zu werden, und während der Relativbewegung eines wiederholten Abtastens des Laserstrahls (2), um einen zweidimensionalen äquivalenten effektiven Laserspot (5) auf dem Oberflächenbereich zu erzeugen. Die Energieverteilung des effektiven Laserspots ist so angepasst, dass diese in einem wärmeempfindlicheren Unterbereich, wie etwa in einem Bereich angrenzend an ein Ölschmierungsloch, anders ist als in einem weniger wärmeempfindlichen Unterbereich, um so ein Überhitzen des wärmeempfindlicheren Unterbereichs zu verhindern.

    Abstract: Procedimiento de endurecimiento por láser de un área superficial de una pieza de trabajo, tal como una superficie de un muñón de un cigüeñal, que comprende: generar un movimiento relativo entre la superficie de la pieza de trabajo y una fuente de láser para permitir que un punto de láser se proyecte posteriormente sobre diferentes porciones de dicha área superficial, y durante dicho movimiento relativo, realizar una exploración de forma repetitiva con el haz de láser (2) con el fin de producir un punto de láser eficaz (5) equivalente bidimensional sobre dicha área superficial. La distribución de energía del punto de láser eficaz se adapta de tal modo que esta es diferente en un área secundaria más sensible al calor, tal como en un área adyacente a una abertura de lubricación de aceite, que en un área secundaria menos sensible al calor, con el fin de evitar el sobrecalentamiento de dicha área secundaria más sensible al calor.
