A luminescence diode chip includes a semiconductor layer sequence having an active layer suitable for generating electromagnetic radiation, and a first electrical connection layer, which touches and makes electrically conductive contact with the semiconductor layer sequence. In such an arrangement by electrostatic interaction between the network elements is produced a parasitic resonance at a frequency different from the operational resonance frequency. The metallic martensitic steel is consolidated to produce a consolidated metallic article, without melting the metallic martensitic steel and without melting the consolidated metallic article.
