When the cycle has commenced, the development of the nitrided case begins with the nucleation of gamma-prime into small “islands” at the interface between the ammonia atmosphere (decomposing) and the component being nitrided.

Many companies are gas nitriding, and the process is 100 years old from the patent date. So, the process is not a new process. It is, however one of the “youngest” processes.

Once again the price of oil is fluctuating. This time, it is decreasing in price. We can rest assured that the price will inevitably increase once again. This means that quench-oil price will also increase.

We are looking to redesign our air-circulating tempering furnace as far as the electrical energy input is concerned. We need to increase the gross load mass in the furnace. Therefore,

When nitriding a steel, it is advisable to have a core with a phase structure of tempered martensite. The tempered martensite will assist with the support of the formed case.

Most plasma nitriding systems in North America have been developed on the basis of continuous DC plasma generation. There are, however, a small number of pulsed-DC plasma-generation systems. The question is often asked which system should I choose?

A recent seminar was held that was focused on gear distortion. While the distortion aspect of the seminar was extremely interesting and very well presented, the impact on the writer

The process of gas nitriding is perhaps the simplest of all of the diffusion surface-treatment processes. The process simply involves the decomposition of ammonia by heat and steel (catalyst).The decomposition

Distortion is the “bane” of all heat treaters. Distortion is always laid at the doorstep of the heat treater. This is simply because distortion always occurs at heat treatment. Because

Plasma CarburizingPlasma carburizing is characterized by two things – plasma generation and low pressure. In order for the gas ionization to take place, it is necessary for the furnace to
