The present invention is directed to compositions for electroless plating baths and their use, and more particularly to different solutions or concentrates each usable to both make up an original bath and to replenishment of the original bath.

Plating bath solutions

The present invention is directed to compositions, baths, and methods for composite plating including polytetrafluoroethylene (PTFE), and more particularly, to compositions, baths, and methods of composite plating with PTFE in a metal or alloy matrix where the materials used in the process contain no or essentially no PFOS (perfluorooctane sulfonate) and/or no PFOA (perfluorooctanoic acid).

Composite PTFE plating

This invention is directed to a process for electrolessly metallizing an article, as well as to a plating bath and the subsequent plated substrate. The process comprises contacting the surface of an article with an electroless metallizing bath which may be essentially free of toxic and/or heavy metals.

Composite electroless plating

The present invention relates to composite electroless coatings with varying densities of codeposited particles in the plated layer along the surface of the substrate where said variation of densities is directed by the angle of rotation of the substrate during the coating process.

Selective codeposition of particulate matter and plated articles thereof

This invention relates to processes for the formation of composite layers containing insoluble particles in metal matrices onto bodies to achieve enhanced thermal properties.

Composite coatings for thermal properties

A process for the codeposition of a composite metallic coating comprising finely divided particulate matter dispersed within metallic matrixes and having a gradient in particle density distribution along the coating thickness. The established gradient ranges from a region of high density of particles to a region of lower density of particles along the coating thickness. The established gradient is affected by the deliberate change(s) in plating parameter(s) during the plating cycle.
