Abstract: A rotor for a reluctance machine includes a rotor body having cavities defined by inner surfaces of the rotor body, a filler disposed within the cavities, and an adhesive coating that covalently bonds the filler to the inner surfaces of the rotor body. The adhesive coating exhibits a composite structure including a continuous matrix component and a discontinuous organic component dispersed throughout the matrix component, wherein the matrix component comprises an inorganic siloxane network and the organic component comprises a plurality of organic groups bonded to the inorganic siloxane network. The adhesive coating is formed on the inner surfaces of the rotor body by depositing a precursor composition on the inner surfaces of a rotor body and exposing the precursor composition to a plasma. The precursor composition comprises an organofunctional silane or a hydrolysate thereof.

Abstract: A method for fabricating an electrode for a battery cell includes supplying a first electrode film from a first roll. The first electrode film comprises an active material for exchanging lithium ions and a binder. The method includes treating a first side of the first electrode film using a first plasma treatment system; supplying a current collector, and heating and pressing the first side of the first electrode film to a first side of the current collector together using first and second rollers.

Abstract: A part formation system includes: a mobile robot; a first material feeding device configured to feed carbon fiber prepreg material, one layer at a time, onto the mobile robot to form a stack of carbon fiber prepreg layers on the mobile robot; a second material feeding device configured to feed a paint film onto the stack of carbon fiber prepreg layers to provide a resultant stack of layers; and a heat press configured to form and cure the resultant stack of layers to provide a resultant painted part by heating and compressing the resultant stack of layers.
