Black oxide is a pleasing surface conversion coating. As stated in past articles, the process dresses steel and other select alloys with a corrosion resistant skin. Although mild in nature,...
This post will address the gas nitriding process and its effects on steel. Essentially, we’ll be looking at a heat treatment technique that addresses alloy hardening concerns and the need...
Process economy is an ideal we chase in heat treatment technology. Masses of fuel and heat are devoured during a hard day’s work inside this manufacturing environment. How does the...
To some extent, worked alloys have memory. Stress can be absorbed and stored in the metal. Under these circumstances, heat treatment facilities call upon the services of a stress relieving...
On one side of this comparative guide, induction hardening technology employs a strong electromagnetic field as the heat treatment engine. On the other side, a similarly potent case hardening station...
Dark black oxide coatings look attractive. Aside from that smoky appeal, there’s another benefit to this technique. Designed to act as a corrosion-resistant finish, black oxide treatments stop ferrous parts...
Numerous variables govern the heat treatment process. If one of those variables moves beyond an allowable error margin, the toughened and tempered workpiece will likely demonstrate a set of less...
The successful utilization of a vacuum heat furnace hangs on several important factors, most importantly of which would be the integrity of this vacant space. Contingent on the purity of...
Metal embrittlement occurs during numerous heat treatment processes. Furthermore, certain electrochemical techniques are known to promote this undesirable effect. The result is a finished metal product that’s drastically weakened. Fracture-prone...
Engineering terms usually help out by subtly suggesting their meanings. If someone talks about a quenching operation, then the process becomes self-evident. But that’s not always the case, certainly not...
Despite appearances, heat treatment work relies on a scientifically accurate process. Sure, the coarse industrial outlines operating here may suggest otherwise, but don’t be fooled, this is engineering fidelity labouring...
Just as a refresher, what is heat treatment technology? Certainly, the exposure of a metal part to heat changes its material and mechanical characteristics. And those changes occur over time....
Carbon is the element upon which all of life is founded. Also, in heat treatment technology, carbon is the primary alloying element in the steel hardening process. Not surprisingly, there...
Certain questions always seem to return to torture novice engineers. No sooner has one problem been solved than the next comes careening down the track like a runaway train. It’s...
When a discussion turns to heat treatment, aluminium isn’t the first metal that comes to mind. We think of its lightweight features, the uses of aluminium alloys as an aeronautics...
Let’s navigate our way through a passivation process that earns its name by producing a blue-black protective layer around the subjected steel part. The heat treatment technique essentially forms a...
Today’s journey through heat treatment technology looks at Austempering. As always, we’re industriously seeking the best, most cost-effective way to improve the mechanical and physical characteristics of a workpiece. More...
It’s tough to case harden low carbon steels. Simply put, more carbon equals more hardness, a feature that even the casual observer can appreciate. One solution to this processing puzzle...
Vacuum heat furnaces perform expeditiously as atmosphere controlled heat treatment chambers. Drained of process-influencing oxygen and filled instead with an inert gas, the furnace stops scaling, stops parts discolouration, and...
Do’s and don’ts guides are an engineer’s best friend. They’re an objective instruction tool that helps system architects and fabricators to navigate processing minefields. In that regard, hot zone maintenance...
Does a factory full of furnaces look like some industrial hell? In point of fact, nothing could be further from the truth. Science-lab accuracy and high-tolerance engineering exactitude rule every...
As stated in our earlier articles, flame hardening technology selectively heats and hardens parts of a metal workpiece. Imagine the teeth of a spur gear being subjected to the flame,...
Metal fabricators employ numerous tooling stations, which is as it should be because complex geometrical profiles are processed within these expert workshops. Some tools bend, others drill, then, waiting in...
The flame hardening process is a cost-effective heat treatment technique. Primarily, it’s the high-intensity oxy-gas flame that keeps project expenditure low. The flame hardens localised workpiece areas, so application economy...
