The cylinder walls of light metal engine blocks are thermally spray coated with a ferrous-based coating using an HVOF device. A ferrous-based wire is fed to the HVOF device to locate a tip end of the wire in a high temperature zone of the device. Jet flows of oxygen and gaseous fuel are fed to the high temperature zone and are combusted to generate heat to melt the tip end. The oxygen is oversupplied in relation to the gaseous fuel. The excess oxygen reacts with and burns a fraction of the ferrous-based feed wire in an exothermic reaction to generate substantial supplemental heat to the HVOF device. The molten/combusted metal is sprayed by the device onto the walls of the cylinder by the jet flow of gases.

An engine piston compression ring designed to reduce the negative effects of ring end butting and reduce blowby. The compression ring has a gap forming an angle with a longitudinal axis of the ring or with a radius drawn from the axis. A relieved portion is provided along the upper or inner side of the ring adjacent one end, depending upon the direction of the gap angle. The relieved portion slopes along the upper or inner side toward the one end where the longitudinal thickness of the ring is smallest.

A nozzle assembly for a HVOF thermal metallic spray coating system includes an inner tube, a middle tube and an outer tube which are concentrically arranged about an axis of the nozzle assembly and are spaced to provide annular, concentric gas flow passages for oxygen and gaseous fuel along with a central wire feed passage in an efficient, compact arrangement. A slotted nib and plug are fitted to the discharge end at the assembly and defined, together with the middle tube, an annular premix chamber for the combustible gases, and a plurality of circumferentially spaced mixing slots and a downstream mix end portion of the nib where complete mixing of the gases occurs prior to entry into the combustion chamber provided in an air cap. An annular passage between the air cap and outer tube communicates with a high pressure air source for establishing an envelope of air against the inside surface of the air cap to serve as a protective barrier layer from the atomized metal.

The cylinder walls of light metal engine blocks are thermally spray coated with a ferrous-based coating including aluminum using an HVOF device. A ferrous-based wire is fed to the HVOF device to locate a tip end of the wire in a high temperature zone of the device. Jet flows of oxygen and gaseous fuel are fed to the high temperature zone and are combusted to generate heat to melt the tip end. The oxygen is oversupplied in relation to the gaseous fuel. The excess oxygen reacts with and burns a fraction of the ferrous-based feed wire in an exothermic reaction to generate substantial supplemental heat to the HVOF device.

The present invention provides a carburizing method that involves heating a steel component quickly to a relatively high carburizing temperature (e. g. 1900 degrees F. and above), contacting the component at the relatively high carburizing temperature with a methane-containing carburization atmosphere for time to form a carbon-enriched surface case on the component, and cooling the component at a relatively slow rate effective to provide a relatively soft martensite-free surface case on the component. The component then is subjected to a hardening treatment wherein the carburized component is heated to a hardening temperature in the austenitic range followed by quenching and tempering to form a tempered martensitic surface case on an underlying non-martenistic core.

A high pressure fluid jet nozzle has a generally cylindrical body with inlet and outlet ends, a through passage with an entry portion extending to at least one laser cut orifice at the outlet end of the body. The body has a smooth outlet end through which the laser is configured entirely by laser cutting. The entry portion of the through passage preferably has a hemispherical end penetrated by the orifice. Manufacturing steps including laser cutting of the orifice or orifices and optional electrical discharge machining of the hemispherical end of the entry portion.

A method for the application of a thermal spray coating to the cylinder wall portions of an aluminum engine block casting is disclosed in which the casting is inverted and water is caused to flow through the cooling passages of the engine block in a series flow from one end of a bank of cylinders to the other while the block is supported on a fixture that seals the cooling passage outlets in the head of the block. The fixture further permits the spray of a metallized coating onto the cylinder walls without adherence of the spray to the fixture or to other portions of the block.

The method of treating the surfaces of malleable light metal cylinder bores or other objects by blasting the surfaces with extremely high water jets for preparing such surfaces for subsequent coating with wear-resistant materials such as a thermal spray coating. The water not only cleans the surface but roughens it to produce a pitted surface with undercuts so that coating material fills the pits and undercuts to provide a smooth layer of coating material with a strong mechanical/adhesive bond.
