| Popis: | A batch of AISI 316L stainless steel bar was produced for orthopedic implant manufacture. The paper purposes a documented chemical homogeneity analysis (CHA) as a mandatory step of the chemical composition compliance practice for metallic bulk biomaterials. The CHA significantly diminishes the type II error risk. In this regard a new procedure was developed for CHA based on ASTM E826 one. The paper support the adequacy of the information mass assigned to spark discharged in argon-atomic emission spectrometry (SDAR-AES) technique. The case study demonstrates the power of this practice to discriminate among the homogenous elemental distribution (Cr, Ni, Si, etc) and heterogeneous (C, P, S). |
