Sulfiding

Part of speech: noun, verb

Definitions

1. The process of treating a metal or material with sulfur or sulfur compounds to improve corrosion resistance ; the chemical reaction where sulfur is combined with another substance to form a sulfide ; an industrial or laboratory procedure involving the application of sulfur to alter surface properties or composition
2. The act of exposing a metal surface to sulfur or sulfur-rich compounds to form a protective sulfide layer ; a method in chemistry where sulfur is introduced to a substance to induce sulfide formation ; a treatment used to modify material characteristics through sulfur addition
3. A technique involving the introduction of sulfur to metals or materials to create a sulfide coating that enhances durability ; the chemical combining of sulfur with another element to produce sulfides ; an application in manufacturing or science for sulfur-based surface modification

Etymology: Sulfiding is a plain technical formation: the word "sulfide" with the suffix "-ing" added to turn it into a noun for the process. "Sulfide" itself is built from "sulf(ur)", the English form of the old word for the element, which came into Middle English from Anglo-Norman "sulfre" and ultimately from Latin "sulfur", with a Proto-Indo-European root of uncertain reconstruction at its deepest layer. The "-ide" ending is a chemical suffix borrowed from Latin "-idus" through French, used to name binary compounds of an element with another substance. The "-ing" that finishes the word is an old English suffix, descended from Proto-Germanic forms that were used to make nouns from verbs and nouns, and it passed through Middle English "-ynge" to the modern "-ing". Because the suffix is so productive, chemists and metallurgists could attach it to any compound name, so "sulfiding" describes the act or result of forming sulfides, whether the target is a metal surface or another material.
