Quality management in heat treatment process

Purpose: The purpose of this paper is to present the specifications of the CQI Heat Treat System Assessment, together with a discussion of the importance, development, implementation and use of this specification. An analysis of the quality management system of the selected organization was performed, which takes care of the thermo-chemical treatment-nitriding, as regards to the specification AIAG CQI-9. The study was carried out to compare the standards based on the scope of the organization covered by individual standards and their hierarchy, where the levels are adequate for the scope of the quality management system. Design/methodology/approach: An assessment of the compliance with the requirements of the CQI-9 based on the criteria closed in the documentation of the specification was performed, by evaluated according to the requirements imposed by the CQI-9, and determining the compliance of the quality system with the requirements determined in the documentation of the specification, with the subscription in the documentation. Findings: As a result of the audit of the nitriding process of selected part of the technology in relation to the requirements of the CQI-9 specification, the deficiencies were identified in relation to the requirements of the CQI-9 specification, and suggestions for their solutions were provided. Research limitations/implications: The paper presents the steps and how to verify the quality management system in the process of heat treatment. Practical implications: The result of the audit specifications CQI-9 detected non-compliance to requirements of the specification. The improvement of the quality management system, with some recommendations, allows to target the activities of the process to the needs and expectations of customers. Originality/value: The paper presents some requirements concerning the quality of the selected part of the thermo-chemical treatment process.
