hydrogen embrittlement उदाहरण वाक्य

The process is also known as dry galvanizing, because no liquids are involved; however, no danger of hydrogen embrittlement of the goods exists.
It can however cause hydrogen embrittlement of many alloys and especially carbon steel, so its application is usually limited only to some stainless steels.
However, iron hydride is metastable and subject to the rapid formation of a precipitated phase of gaseous dihydrogen, a process known as hydrogen embrittlement.
In the 1980s, the pressure tubes in the Pickering A reactors were replaced ahead of design life due to unexpected deterioration caused by hydrogen embrittlement.
The cause of cracking did not become clear until metallographic results were combined with stress corrosion cracking and hydrogen embrittlement tests, followed by fracture mechanics analysis.

The greatest advantage of the process is its ability to overcome hydrogen embrittlement problems, which is important for workpieces that have a hardness greater than HRC 40.
However, in some circumstances & mdash; where there is a risk of hydrogen embrittlement, for example & mdash; this lower voltage is advantageous, as overprotection is avoided.
The uranium oxide is dried before inserting into the tubes to try to eliminate moisture in the ceramic fuel that can lead to corrosion and hydrogen embrittlement.
An additional problem is that any excessive hydrogen ions as a result of an excessively negative potential can cause hydrogen embrittlement of the wire, also resulting in failure.
There is a great cost savings in using mechanical plating over electroplating on hardened workpieces, because the electroplating processes requires a pre-and post-plating operation to overcome hydrogen embrittlement problems.
