in my study ,coatings grain size must be characterized and calculated and the only way i readabout is XRD .in literature there are several methods (on what base?I don’t know) . on theother hand , they mentioned (texture) for the metal deposits .what is texture andwhat is related to? O "The successive texture axes [101] and [21 l] on increasing J preferably appear in the Ni deposits in a NiCl, bath…..". يعني مثل هذه المفردات أقرأ عنها و نفسي أفهمها بشكل مبسط (يعني بالعربي كذة) و ليس فقط آخذها كما هي أو كترجمة حرفية
