Types of surface heat treatment processes
Types of Surface Heat Treatment Process
Surface heat treatment, or surface engineering, is a process used to make changes to the properties of a material without altering its bulk properties by altering its surface properties. This process is commonly used to improve wear resistance, increase hard......
Metal Surface Treatment
Metal Surface Treatment Methods
The performance of many metal components is affected by the surface treatments they undergo. The aesthetics, wear characteristics and corrosion resistance of various components can be modified and improved by various surface treatments such as coating, metallizing ......
Self-molding electroslag remelting
Self-fusing Mold Electric Slag Remelting
Self-fusing Mold Electric Slag Remelting (SFMERS) is a process used in metal working and manufacturing to quickly remelt and recycle metal scrap, without the use of heat or expensive furnace equipment. The process is most commonly used when dealing with lar......
Defects and countermeasures of large forgings: segregation
Defects and Countermeasures for Large-scale Forgings
Defects that often occur when forging large push pieces are mainly caused by improper technical measures, die design and material selection, such as misalignment between billet and die, die forging defect, die forging process defect, forging mat......
Typical defect of forgings of alloy structural steel and alloy tool steel-essential coarse and uneven grain size
Typical defects of forging parts of alloy structural steels and alloy tool steels -- Uneven macrostructure
Alloy structural steels and alloy tool steels are widely used in aspects such as mechanical and armaments manufacturing, civil engineering and so on. Forging is one of the important processe......
Forging technology: precipitation hardened stainless steel forging
Introduction
Precipitation hardening stainless steel forging is a forging method that uses precipitation hardening stainless steel as a material and is processed by forging. Forging can be divided into hot forging, warm forging and cold forging according to the temperature range of the processing......
Forging Technology: Die Forging Features of Screw Presses
INTRODUCTION
Spin pressure forming technology refers to the realization of some plastic deformation without high temperature under the action of pressure and radial force generated by rotating pressure head. The spin pressure deformation technology can be used in various fields such as automobile......
Forging Basics
Introduction
Forging, also known as metalworking, is an industrial process by which metal is heated and then shaped into various objects. The process of forging involves heating metal until it is malleable and then hammering it into the desired shape. The forging process has existed since ancient......
metal degassing
Introduction
Metal degassing is a process that involves the removal of unwanted gasses from metals. The goal of metal degassing is to make the metal free from hazardous and corrosive gasses such as oxygen, nitrogen, hydrogen and chlorine. Metal degassing is used in a number of industries, such as......
