INTRODUCTION

Corrosion can be prevented by various methods One of them is to convert the surface layer of the metal to form a layer of oxides The process of corrosion by virtue of the chemical reaction by the oxidants with activators forms oxides of the corresponding metal and ultimately the material is destroyed KNITCOR process gives excellent resistance against wear corrosion Scuff Fatigue etc on ferrous components and safeguard from the destruction of the components

PROCESS PROPERTIES: KNITCOR process oxidizes some of the nitrides formed on the surface of the ALFA NITROCABURISED components to a well knit type of spinel oxides FeOFe3O4 This layer is very much helpful in industrial use as pockets for oil retention by which the lubrication property can be improved KNITCOR process can replace the plating processes like Hard Chrome Cd Zn Ni etc

The corrosion resistance obtainable is upto 200 hours asper ASTM B 117 and is superior to those by plating protection like Zn Cd Cr etc

KNITCOR process can be used to replace expensive alloy steel components meant for corrosion resistance KNITCOR treated components have a pleasing black colour The operating temperature of the bath is 420 430 C KNITCOR Quench Polish Quench Liquid Nitriding quench in Oxidation bath polish quench in oxidation bath plays an important role in Wear and sliding friction of surface engineering KNITCOR produces excellent sliding along with high wear resistance and running properties The KNITCOR processed components when conducted with wear tests and practical applications confirm benefits over other surface engineering processes particularly under adhesive load KNITCOR Quench Polish Quench process increases fatigue strength about 100 on notched components made from unalloyed steel parts and about 3080 on parts made of alloyed steels The hardness is maintained up to about 1200 HV and extends the surface life of steel tools and components exposed to heat

The coefficient of friction both under dry conditions and after lubrication with DW 940 oil measured by an Amsler machine All samples were lapped to a roughness of Rt 2 3 m after their respective surface treatments and before testing Without lubrication the KNITCOR Quench Polish Quench had the lowest coefficient of friction being less than half of that of the hard chrome plated or casehardened surfaces The lowest friction level occurred when KNITCOR Quench Polish Quench is lubricated It is 34 times lower than that achieved with the chrome or martensitic surfaces

Hardness and wear resistance of the surface Perhaps the most significant enhancement is that the QPQ method forms a strong wearresistant coating on the surface of materials greatly improving their resistance to abrasion friction and pressure This is accomplished by diffusing carbon and nitrogen into the materials surface forming a tougher compound layer than the primary material
Corrosion resistance QPQ coatings are highly successful in protecting materials from corrosion especially in hostile situations such as high humidity marine or chemical conditions The nitride layer created during the QPQ coating operation is a corrosion barrier preventing corrosive substances from penetrating the material
Fatigue strength Generally materials that undergo the QPQ process have greater fatigue resistance often seen as the tendency of materials to fracture or break in the face of repetitive stress or repeated loading The QPQ method forms a compressive stress layer on the materials surface which enhances fatigue resistance
Friction and lubricity The QPQ process may also increase a materials lubricity and friction making it more wearresistant and decreasing friction between moving components The way to accomplish this is by smoothing the materials surface to minimize the degree of roughness and increase the surfaces capacity to retain lubricants
Dimensional and surface finish control QPQ coatings may be applied with great accuracy providing tight tolerances and exceptional quality monitoring for the materials surface One great application is in situations requiring exact measurements and flawless surface finishes
If a uniform running behavior is required the KNITCOR process is appropriate Lubrication has only a slight influence on the coefficient of friction because the oxide layer of the outer surface was removed during the polishing operation
It has been determined that unlike with chrome surfaces the coefficient of friction of nitrocarburized ALFANIT treated surfaces remains constant even at varying sliding speeds It is a thermochemical treatment for improving the surface properties of steel parts It exhibits predictable and repeatable results in the treating of low and medium carbon steels alloy steels stainless and austenitic steels tool and die steels cast and sintered iron
