A process of electrolessly metallizing a body on the surface thereof with a metal coating incorporating particulate matter therein, which process comprises contacting the surface of said body with a stable electroless metallizing bath comprising a metal salt, an electroless reducing agent, a complexing agent, an electroless plating stabilizer, a quantity of particulate matter which is essentially insoluble or sparingly soluble in the metallizing bath, and a particulate matter stabilizer (PMS), and maintaining said particulate matter in suspension in said metallizing bath during the metallizing of said body for a time sufficient to produce a metallic coating with said particulate matter dispersed therein.

Stabilizers for composite electroless plating

The invention provides a method for the metallizing of precision machine parts coupled with heat-treatment and machining to insure the minimal handling the remachining generally required due to dimensional distortion resulting from the standard heat-treatment used in hardening the metallized coating.

Method for manufacturing metallized heat treated precision articles

Non-ionic stabilizers in composite electroless plating

This invention discloses processes and articles for the manufacturing of composite plated articles comprising finely divided particulate matter dispersed within metallic matrices and having light emitting properties, such articles being useful in the metallization of articles and their reuse through subsequent rejuvenation, without damaging the base metal of said articles.

Composite plated articles having light-emitting properites

Disclosed is a method for the coating of textile spinning machinery parts with a composite coating bearing finely divided lubricating particles dispersed within a hard metallic matrix. The lubricating particles are particulate matter capable of withstanding heat-treatment temperatures of at least 300.degree. C. without their degradation.

Lubricated textile spinning machinery parts

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.

Composite plating having a gradient in density of codeposited particles

A process for the selective variation in density of particulate matter codeposited within metallic matrices deposited onto articles utilizing increased levels of rotation of said articles during plating cycle to attain said selective codeposition density. The attainment of varying densities of codeposited particulate matter in the plated layer along the surface of the substrate is particularly useful in cost reduction and improved product performance.

Selective codeposition of particulate matter and composite plated

Disclosed herein are processes for the metallizing of an article to provide on the surface thereof a metallic coating free of codeposited particulate matter comprising the contacting of said article with a metallizing composition having dispersed therein finely insoluble particulate matter which are not codeposited within said metallic coating during the plating process. Said process provides an improved surface morphology in comparison to the metallic coating derived from said metallizing composition in the absence of said insoluble particulate matter.

Process for attaining metallized articles

Disclosed is a method for the plating of a substrate with a composite coating bearing a metallic matrix with finely divided particulate matter dispersed therein. The plating bath is derived by the admixing of a prestabilized particulate matter composition or a precursor thereof along with the required plating chemicals. The use of a prestabilized particulate matter composition offers a convenient way of shipping treated powders devoid of liquids and thereby minimizing shipping costs and aging effects commonly associated with liquid dispersions. The use of the novel prestabilized particulate matter composition along with the plating chemistry provides results substantially the same as those observed from freshly prepared liquid dispersions and their incorporation along with the plating chemicals.

Prestabilization of particulate matter prior the dispersion

Composite plated articles having light-emitting properties

Disclosed herein is process method and articles of plated coating having functions ranging from wear resistance, lubricity, corrosion resistance, and further incorporating therein particulate matter having light emitting properties. Having this codeposited light emitting particles within the functional layer provides a signal for the determination of the presence of the coating and its stage of deterioration.

Functional coatings comprising light emitting particles

A process for the electroless deposition of metals and alloys onto a substrate by immersion of the substrate into an electroless plating composition. Said electroless plating composition comprises a solvent, a metallic compound, an electroless reducing agent, a complexing agent and/or chelating agent, and a compound comprising cobaltic ions. The presence of the cobaltic ions assists in the stabilization of this composition of matter.

Prestabilization of particulate matter prior to their dispersion

A process of electrolessly metallizing a body on the surface thereof with a metal coating incorporating particulate matter therein, which process comprises contacting the surface of said body with a stable electroless metallizing bath comprising a metal salt, an electroless reducing agent, a complexing agent, a quantity of particulate matter which is essentially insoluble or sparingly soluble in the metallizing bath, and a particulate matter stabilizer (PMS), and maintaining said particulate matter in suspension in said metallizing bath during the metallizing of said body for a time sufficient to produce a metallic coating with said particulate matter dispersed therein.
