96.42 ± 0.97. Before sintering, delubrication was carried out in conventional vacuum furnace at 350°C for 6hrs in vacuum range of 10-2 to 10-3 Torr. The microwave sintering was carried out using 2.54Hz, 6kW multimode furnace in vacuum, nitrogen, argon and hydrogen, respectively at temperature ranging
The C.I. Hayes "CVCQ-LAM" Vacuum Sintering Furnace uniquely combines atmosphere delubrication and vacuum sintering. An in-line atmosphere delube/preheat section and integral vacuum sintering chamber allow for processing of powder metal (P/M) compacts at conventional or high temperatures.
Powder metallurgy (PM) is a term covering a wide range of ways in which materials or components are made from metal powders.PM processes can avoid, or greatly reduce, the need to use metal removal processes, thereby drastically reducing yield losses in manufacture and often resulting in lower costs.
Nitrogen gas generators allow companies to take control of their own gas supply and reduce their costs considerably. Integrated nitrogen generation systems from Parker use air from a standard industrial compressor that is essentially 'sieved' so that oxygen and other trace gases are removed, while nitrogen is allowed to pass through
This work aims to study sintering of elemental titanium and pre-alloyed Ti-6Al-4V powders in a graphite furnace which is operated with back-filled argon. The specific task is to investigate the effect of carbon, oxygen and nitrogen contamination in the furnace atmosphere during sintering.
MESH BELT FURNACES FOR PRECISION SINTERING (FW SERIES) Manufactured by a highly skilled workforce with decades of experience, the FW series sintering furnaces are designed specifically for very high uptime. Several installations have been in continuous operation for years on end with production interrupted only for a (hot) belt change.
Maintaining Optimal Atmospheres in Sintering Furnaces . The actual sintering takes place in the high-heat sintering furnace under a hydrogen, or in some applications, a hydrogen-nitrogen atmosphere at temperatures above 2400 °F (1300 °C).
Camco Hydrogen Furnaces. By operating in hydrogen or any reducing/inert atmosphere up to 2100°C, Camco's positive pressure coldwall furnaces are an ideal solution to many high temperature processes that require an oxygen-free environment. Easily and reliably ramp up to desired temperature in minutes or days, depending on your requirements.
Powder metal sintering requires specific gas atmospheres in order to assist de-lubrication and to avoid decarburization. In addition to supplying the required gases such as nitrogen, hydrogen and carbon monoxide, we offer leading technologies to control the carbon potential and the uniformity of the sintered parts.
Belt Furnace for Sintering of PM-parts under an atmosphere of endogas or nitrogen/hydrogen . MAHLER Belt Furnace for brazing and annealing of mild steel parts under exogas atmosphere. Due to the integrated protective gas generation inside the furnace MAHLER Exogas Furnaces belong to the most economic heat treatment plants available on the market.

Application of nitrogen argon inert atmosphere muffle furnace . 1) laboratory heat treatment with some atmosphere gas (N2,Ar,H2,O2) 2) Ceramics sintering and metal melting. 3) Preheating,Quenching,annealing,temperaing, and normalizing. Features of nitrogen argon inert atmosphere muffle furnace . 1) Double stainless steel shell with fans cooling
The increasing costs of energy and the variations in hydrocarbon composition have increased the interest in the heat treatment of steels with nitrogen based atmospheres. Recently, new processes have been developed using nitrogen and small additions of fluids. The nitrogen-methanol process enables a pure carrier gas to be used.
Nabertherm does not only offer the widest range of standard furnaces. Professional engineering in combination with in house manufacturing provide for individual project planning and construction of tailor-made thermal process systems with material handling and charging systems. Complete thermal processes are realized by customized system solutions.
Once the debinding step is completed, the components are laid into a sintering furnace where they are heated until they reach a temperature which is lower than the melting temperature of the metal powder's main constituent. During this process, the powder mass bonds and this allows to achieve a near full density component.
A laboratory tube furnace was used for the sintering experiments. Dewaxing was done at 600°C for approximately 25 minutes and sintering was performed at 1120°C for 30 minutes in all experiments. A mixture (90/10) of nitrogen and hydrogen was used as process atmosphere and the partial
