English term or phrase: pesting/pest
Hi there, does someone know the translation for pesting/pest in this context? I´ve researched all glossaries and dictionaries without luck.
I found these sites in English:

Here is the context paragraph:
- However, at low temperatures, the molybdenum oxide will remain in the surface layer and will therefore disturb the formation of a continuous silicon dioxide layer. This may lead to a continuous consumption of the material (MoSi2) of the heating element. This phenomenon is called "pesting" or "pest". -

(secuencia/fenómeno) PEST

Me da la sensación, por lo que he visto en este artículo, que “PEST” podría ser un acrónimo, por lo que se mantendría tal cual en castellano (con las mayúsculas). Pero que me corrijan los que tengan más conocimientos de química, yo soy de letras :-)

“PEST” degradation in beryllides, silicides, aluminides, and related compounds

Many intermetallic compounds, although possessed of good oxidation resistance at low and high temperature, fail catastrophically in some intermediate range by degradation to powder — the so-called pest phenomenon.
A PEST sequence is a peptide sequence that is rich in proline (P), glutamic acid (E), serine (S), and threonine (T). This sequence is associated withproteins that have a short intracellular half-life; hence, it is hypothesized that the PEST sequence acts as a signal peptide for protein degradation.[1]
Una secuencia PEST es una secuencia peptídica rica en residuos de prolina (P), ácido glutámico (E), serina (S), y treonina (T). Dicha secuencia se asocia con proteínas que tienen una vida media celular corta; de ahí que se hipotetice que la secuencia PEST actúa como péptido señal paradegradación proteolítica.1

Y por extensión, "PEST"ing

However, MoSi2 has a few undesirable properties like ‘PEST’ing, low fracture
toughness at low temperatures and low creep resistance at high temperatures.

Asker: Gracias Sara, estuve leyendo pero estoy seguro que se trata de una palabra en otro ámbito distinto. Saludos cordiales

Reference information:
La llamada peste del estaño es un fenómeno muy particular de este elemento químico, el cual tiene una gran sensibilidad ante bajas temperaturas. Expuesto a la influencia de éstas, el estaño “enferma”. En lugar de blanco argénteo adquiere color gris, aumenta de volumen (alrededor de un 26%), comienza a desmenuzarse y con frecuencia se convierte en polvo. La terminología que se emplea para denominar a este fenómeno, conocido desde hace siglos, es la peste del estaño, y también es a veces llamado lepra o enfermedad del estaño. El estaño "enfermo" puede "contagiar" al metal sano, de ahí la denominación de pesteño

Tin pest is an autocatalytic, allotropic transformation of the element tin, which causes deterioration of tin objects at low temperatures. Tin pest has also been called tin disease, tin blight or tin leprosy (lèpre d'étain).

Asker: Gracias, lo que estaba viendo es que es muy exclusiva para el estaño, en este caso se trata de otro material. Saludos cordiales
