High-activity carburizer for carburizing
Metal Science and Heat Treatment, 19791. The addition of polycaproamide to a carburizer consisting of soot and sodium carbonate greatly speeds up the carburizing process. 2. Carburizing steels 3Kh13, ShKh15, and KhVG in carburizer containing polycaproamide makes it possible to obtain a case with as much as 4% C with a wear resistance 250–300% higher than that of quenched ...

Carburization - introductory survey
Materials and Corrosion, 1998This survey revisits the research in Germany in the seventies and eighties on carburization conducted in a fine cooperation of research institutes and a supplier of high temperature alloys, funded in the programme FEKKS by the BMFT. The kinetics and mechanism of the carburization of high alloy Cr-Ni-steels and the main reasons for failure were ...

Thermochemical treatments carried out in microwave plasma are applied to steel substrates to increasehardness and prevent corrosion and simultaneously improve wear resistance. They are efficient for steelcarburizing. Since they are electrodeless process, the steel is free from metallic sputtering.

Advances in Carburizing — Vacuum Carburizing
1985Steel components having appropriate combinations of wear resistance, mechanical strength, impact strength, etc., especially at higher temperatures (above 500°F) can be produced by employing the well-known conventional carburizing process or a suitably modified process.

AbstractThe plasma carburizing process is basically a low-pressure carburizing process making use of a high-voltage electrical field applied between the load to be treated and the furnace wall producing activated and ionized gas species responsible for carbon transfer to the workpieces. This article begins with an overview of the theoretical background

Abstract Gas (atmosphere) carburizing is the de facto standard by which all other surface hardening techniques are measured and is the emphasis of this chapter. Initially, the chapter describes the process and equipment for gas carburizing. This is followed by sections discussing the processes involved in quenching, hardening, tempering,

Carburization behaviour of high temperature alloys in carburizing environment
Journal of Nuclear Materials, 1989Abstract In studying the carburization behaviour of high temperature alloys, tests in a heavily carburizing environment were performed several potential candidate alloys for use in the HTGR system. The carburization tests were carried out in Ar containing 10% CH 4 gas at 800, 850, 900 and 950 °C for up to 100 h.

Carburizing: Microstructures and Properties explains how to recognize and address problems associated with case carburizing treatments for steels. It examines the nature of internal oxidation, decarburization, free carbides, and retained austenite and their effect on fatigue and fracture strength, wear resistance, impact toughness, hardness, and other ...
