摘要:
A system for sulfide stress cracking testing comprises an enclosed testing chamber including a fluid bath comprising a liquid saturated with hydrogen sulfide gas. In addition, the system comprises a test fixture disposed in the testing chamber and at least partially submerged in the fluid bath. The test fixture includes a housing having an internal chamber in fluid communication with the fluid bath and a test assembly disposed in the internal chamber. The test assembly comprises a first upper support and a second upper support, a first lower support and a second lower support, and a first platen engaging each of the upper supports and adapted to transfer an applied vertical load to the upper supports. Further, the system comprises a test specimen mounted in the test assembly between the upper supports and the lower supports.

摘要:
A method of protecting an element from excessive surface wear is provided. In this method, a localized area of the element that will be subjected to excessive surface wear is exposed to induction heating for a period sufficient to heat the localized area to an elevated temperature at which the localized area undergoes austenitic transformation. The localized area is quenched, followed by tempering, and then cooling. A result of the method is a localized hardened area formed monolithically with the element and having a localized hardness that is greater than a base hardness of the element.
