1. A planar inductor for progressive surface layer hardening, the planar inductor comprising:
- a carrier;
an induction coil that is disposed at least partially in a first side of the carrier, wherein the induction coil is exposed and is configured as a conductor loop; and
at least two spacing elements that are arranged at a distance from each other, wherein the at least two spacing elements are coupled to the carrier and protrude beyond the carrier and beyond the conductor loop.

Abstract
The present invention relates to a planar inductor for progressive case hardening, comprising a carrier and an induction coil, which is accommodated by the carrier and exposed on a first side of the carrier and which is in the form of a conductor loop. According to the invention, the inductor comprises two spacing elements, which are space apart from one another and inserted into the carrier and which protrude from the carrier and beyond the conductor loop on the first side. The invention further relates to a preferred method for producing the planar inductor.

12. A planar inductor configured to be positioned parallel to a surface to be hardened of a metallic workpiece, for progressive surface layer hardening the surface to be hardened, the planar inductor comprising:
-
a carrier; an induction coil disposed on a first side of the carrier and residing in a first plane, the carrier and induction coil being configured to be positioned such that, the first plane in which the induction coil resides is parallel to the surface to be hardened, and the induction coil is spaced apart from the surface to be hardened in an unobstructed fashion; and a plurality of spacing elements that protrude from the carrier and are configured to prevent contact between the induction coil and the surface to be hardened. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
