Abstract: A method for manufacturing an electrical contact pad, including a pad mounting and at least one contact layer, and a method for manufacturing an electrical contact, including a contact mounting and at least one contact layer are described. The methods include a step of depositing, via cold gas dynamic spraying, a first powder onto the pad or contact mounting so as to form the contact layer, the first powder containing at least particles including grains made of at least one refractive material, the grains being built into a matrix made of conductive metal selected from among silver or copper. The pads and the electrical contacts obtained in the respective manufacturing methods are also described.

Abstract: Method of using a material including a conductive metal matrix and magnetic entities representing between 8 and 80% by weight of the material and including hard magnetic phases, the magnetic entities being non-magnetized but capable of being magnetized in an average orientation defined by the direction of a magnetic field applied to the material, in order to blow an electric arc between two electrical contact pads, at least one of which includes the material.
