Method of programming the nitinol springs in the space of the kiln chamber

Abstract

W artykule opisano sposób programowania sprężyn z NiTinolu z wykorzystaniem pieca z atmosferą azotu technicznego. W ramach artykułu opisano metodykę procesu. W jej skład wchodzi metoda przygotowania form ze sprężynami, obliczenia numeryczne początkowych nastaw pieca oraz opis procedury wygrzewania w atmosferze azotu. Praca została podsumowana badaniami odwzorowania kształtu sprężyny po procesie programowania.

This paper shows a method of programming the NiTinol springs by heating them up in the furnace chamber filled with technical nitrogen. A fully specified methodology, which consists of preparing the spring forms, the numerical analysis of the heating time and the description of the heating process are presented in this article. The effectiveness of the following method is confirmed using research of shape retention after a series of duty cycles performed by an activated NiTinol spring.
