  • Surface coatings - glossary of terms
    which are exothermic F Fatigue A cumulative effect causing a metal to fail after repeated applications of stress none of which exceeds the ultimate tensile strength The fatigue strength or fatigue limits is the stress that will cause failure after specified number cycles Flame hardening The localised surface heating of a medium carbon steel by an impinging gas flame so that the temperature is raised above 900 o C The part is quenched or self quenches by virtue of the remaining cool bulk of the component and tempered to produce a hard martensitic structure at the surface Flame spraying A thermal spraying process in which the particles are heated and accelerated in a flame produced from the combustion of oxygen and fuel Filler A solid inert material added to a synthetic resin or rubber either to change its physical properties or simply to dilute it for economy Fretting Surface damage caused by very small relative movement between two surfaces usually under heavy load Fused and crushed powder Powder formed from a fused solid mass which is then crushed to the appropriate size for spraying G Galling Damage to the surfaces of materials sliding in contact with each other usually caused by the localised welding together of high spots Common for materials like stainless steel aluminium alloys and titanium Gas carburising See Carburising Gas flow rate The flow rate of gas eg litres per minute through the spraying torch Gas nitriding see Nitriding Gas nitrocarburising See Nitrocarburising Galvanising A hot dip process for deposition of zinc for galvanic corrosion protection of steel Gold plating The electrolytic deposition of gold for decorative or electrical applications Grit blasting A pressurised stream of hard metal or oxide grit material used to clean and or roughen surfaces prior to coating H Hard Chrome plating The electrolytic deposition of chromium to form a very hard 1000Hv tough coating with good wear resistance The structure is micro cracked Hardfacing The application of a cladding or coating of material designed to resist wear Hardness test A test designed to assess the resistance to penetration from a load The surface is indented under a defined load and the depth of penetration is observed High Velocity Oxy fuel Spraying HVOF A Thermal spray process The spray powder particles are injected into a jet formed by the combustion of oxy fuel heated and accelerated to the workpiece HIPPING The high temperature high pressure consolidation of a powder metallurgy component or thermally sprayed coating Density is greatly increased and metallurgical changes provide enhanced corrosion and wear properties HVOF See High Velocity Oxy fuel spraying I Induction hardening The localised surface heating of a medium carbon steel by an induction coil so that the temperature is raised above 900 o C The part is quenched or self quenches by virtue of the remaining cool bulk of the component and tempered to produce a hard martensitic structure at the surface Ion Implantation A process in which a beam of positive ions is projected towards and into the surface It is carried out in partial vacuum and the ions diffuse into the surface layer of the substrate Typically this is carried out with nitrogen giving a nitrided effect Ion nitriding Also called plasma nitriding A vacuum glow discharge technique of nitriding See Nitriding Ion plating A process in which positive ions produced in a glow discharge are attracted to the substrate which is connected as the cathode The ions are typically made by evaporation J K L Laser alloying The application of a powder to a surface followed by fusing and alloying into the surface via the heat from an impinging laser Laser glazing The melting and quenching of a surface to form a fine grained structure or glaze Laser hardening The localised surface heating of a medium carbon steel by an incident laser so that the temperature is raised above 900 o C The part is quenched or self quenches by virtue of the remaining cool bulk of the component and tempered to produce a hard martensitic structure at the surface LPPS See Vacuum or Low Pressure Plasma Spraying M Magnetron sputtering See Sputtering In this PVD process the sputtering action is enhanced by intense magnetic fields Micrograph A micrograph is produced when a section of the coating is taken polished to show the particulate layers and then photographed through a microscope Mechanical bonding Usually represented by mechanical interlocking of the deposited particles with the rough heights on the substrate surface produced during grit blasting Metallurgical bonding Produced by chemical bonding between areas of the coating and substrate in intimate contact or even by diffusion interaction between the coating and substrate Metallurgical bonding can be enhanced by post spraying diffusion heat treatments Micro hardness The hardness of a coating as measured on a microscopic scale Microtrack A device for measuring powder particle size distributions N Nickel plating The electrolytic deposition of nickel to forma corrosion barrier or to reclaim a worn part Can also include hard ceramic particles to from a wear resistant composite coating Nitriding The diffusion of nitrogen into alloy steel to form hard nitrides in the surface layer typically 250µ Performed at between 500 and 750 o C from a gas salt bath or plasma glow discharge Nitrocarburising The diffusion of nitrogen and carbon into alloy steel or mild steel to form hard nitrides in the surface layer typically 250µ Performed at between 500 and 750 o C from a gas salt bath or plasma glow discharge O Oxidation Chemical reaction between the surface elements and oxygen causing oxides of the elements to be formed Oxidising The production of a stable oxide layer on a steel component by heating in a controlled atmosphere Provides corrosion protection and reduced friction P Pack carburising See Carburising Painting The application of organic based layers acrylics etc for corrosion protection and decorative purposes Particle chemistry The elements contained within the particles of a spray powder Passivating The post treatment usually by chromating of nickel cadmium
