Resumen:
Accelerated degradation tests (ADT) are widely used in the manufacturing
industry to obtain information on the reliability of components and
materials, by degrading the lifespan of the product by applying an
acceleration factor that damage to the material. The main objective is
to obtain fast information which is modeled to estimate the
characteristics of the material life under normal conditions of use and
to save time and expenses. The purpose of this work is to estimate the
lifespan distribution of gold nanoparticles stabilized with lipoic acid
(GNPs@LA) through accelerated degradation tests applying sodium chloride
(NaCl) as an acceleration factor. For this, the synthesis of GNPs@LA was
carried out, a constant stress ADT (CSADT) was applied, and the
non-linear Wiener process was proposed with random effects, error
measures, and different covariability for the adjustment of the
degradation signals. The information obtained with the test and analysis
allows us to obtain the life distribution in GNPs@LA, the results make
it possible to determine the guaranteed time for possible
commercialization and successful application based on the stability of
the material. In addition, for the evaluation and selection of the
model, the Akaike and Bootstrapping criteria were used.
