Components of a vehicle airbag gas generator, or inflator, are coated with reactivity resistant materials to protect them from deterioration caused by contact with the high temperature, reactive gases generated by recently developed non-azide high reactive temperature gas generating materials. Suitable coatings include those produced from ceramics and reactivity resistant metals. These coatings also provide long term protection of the components from deterioration caused by the environment/atmosphere within the inflator.
