Gas Nitriding Is A Case Hardening Process In Which Nascent Nitrogen Is Diffused Into The Surface Of A Solid Ferrous Alloy. It Gives Excellent Wear Resistance, Hardness Upto 70 Rc, I.e. 950 To 1150 VPN Is Possible.

Gas Nitriding Is Performed On Finished Components.It Gives Excellent Corrosion Resistance Against Humid Air & Water.It Is A Case Hardening Process & Hence Core Can Remain Tough.

Gas Nitriding Is Done On Alloy Steel Which Contains Aluminum, Chromium, Tungsten & Molybdenum. Mo Reduces The Risk Of Embitterment At Nitriding Temperature. Nickel, Copper, Silicon & Manganese Do Not Give Any Advantages Of Nitriding Nitriding Properties.Gas Nitriding Is Not Done On Carbon Steel Except For Corrosion Resistance Properties. Alloy Having Aluminum Gives Maximum Hardness & Wear Resistance.

A muffle Furnace In Historical Usage Is A Furnace In Which The Subject Material Is Isolated From The Fuel And All Of The Products Of Combustion Including Gases And Flying Ash. After The Development Of High-temperature Electric Heating Elements And Widespread Electrification In Developed Countries, New Muffle Furnaces Quickly Moved To Electric Designs.

Today, A Muffle Furnace Is A Front-loading Box-type Oven Or Kiln For High-temperature Applications Such As Fusing Glass, Creating Enamel Coatings, Ceramicsand Soldering And Brazing Articles. They Are Also Used In Many Research Facilities, For Example By Chemists In Order To Determine What Proportion Of A Sample Is Non-combustible And Non-volatile . Some Digital Controllers Allow RS232 Interface And Permit The Operator To Program Up To 126 Segments, Such As Ramping, Soaking, Sintering, And More. Also, Advances In Materials For Heating Elements, Such As Molybdenum Disilicide, Can Now Produce Working Temperatures Up To 1, 800 Degrees Celsius Which Facilitate More Sophisticated Metallurgical Applications.

The Term Muffle Furnace May Also Be Used To Describe Another Oven Constructed On Many Of The Same Principles As The Box Type Kiln Mentioned Above, But Takes The Form Of A Long, Wide, And Thin Hollow Tube Used In Roll To Roll Manufacturing Processes.

Both Of The Above Mentioned Furnaces Are Usually Heated To Desired Temperatures By Conduction, Convection, Or Blackbody Radiation From Electrical Resistance Heating Elements. Therefore There Is (usually) No Combustion Involved In The Temperature Control Of The System, Which Allows For Much Greater Control Of Temperature Uniformity And Assures Isolation Of The Material Being Heated From The Byproducts Of Fuel Combustion.

carburisingis Aheat Treatmentprocess In Whichironorsteelabsorbscarbonliberated When The Metal Is Heated In The Presence Of A Carbon Bearing Material, Such Ascharcoalorcarbon Monoxide, With The Intent Of Making The Metal Harder. Depending On The Amount Of Time And Temperature, The Affected Area Can Vary In Carbon Content. Longer Carburizing Times And Higher Temperatures Typically Increase The Depth Of Carbon Diffusion. When The Iron Or Steel Is Cooled Rapidly Byquenching, The Higher Carbon Content On The Outer Surface Becomes Hard Via The Transformation Fromaustenitetomartensite, While The Core Remains Soft And Tough As Aferriticand/orpearlitemicrostructure. This Manufacturing Process Can Be Characterized By The Following Key Points: It Is Applied To Low-carbon Workpieces; Workpieces Are In Contact With A High-carbon Gas, Liquid Or Solid; It Produces A Hard Workpiece Surface; Workpiece Cores Largely Retain Theirtoughnessandductility; And It Producescase Hardnessdepths Of Up To 0.25 Inches (6.4mm). In Some Cases It Serves As A Remedy For Undesireddecarburizationthat Happened Earlier In A Manufacturing Process.

Gas Nitriding Surface Is Used For Nitriding Of Various Components Such As Auto Parts, Precision Turned Components, Construction Machinery Parts And Any Other Component Needing Nitriding.
