Overview
| This standard identifies the competences you need to carry out material finishing operations by physical or chemical vapour deposition processes, in accordance with approved procedures. You will be expected to confirm with the authorised person, such as your immediate supervisor, that the equipment is ready for the coating operations to be performed and that all the required components/materials and consumables are available. You will be required to operate the physical or chemical vapour deposition coating equipment, in line with safe working practices and approved procedures, continuously monitoring the coating operations and where necessary, making minor adjustments or seeking help from the authorised person to make the required adjustments, in order to ensure that the work output is to the required quality. Meeting production targets will be an important issue and your production records must show consistent and satisfactory performance. Your responsibilities will require you to comply with organisational policy and procedures for the physical or chemical vapour deposition activities undertaken and to report any problems with these activities that you cannot personally resolve, or are outside your permitted authority, to the relevant people. You will be expected to work to instructions, with a minimum of supervision, taking personal responsibility for your actions and for the quality of the work that you carry out. Your underpinning knowledge will be sufficient to provide a sound basis for your work and will enable you to adopt an informed approach to applying physical or chemical vapour deposition procedures. You will have an understanding of the physical and chemical vapour deposition coating process and its application and will know about the equipment, materials and consumables in adequate depth to provide a sound background for carrying out the activities, recognising and reporting coating defects and ensuring that completed components are to the required specification. You will understand the safety precautions required when working with physical or chemical vapour deposition equipment and materials. You will be required to demonstrate safe working practices throughout. You will also understand your responsibilities for safety and the importance of taking the necessary safeguards to protect yourself and others in the workplace. |
Performance criteria
You must be able to:
| 1. work safely at all times, complying with health and safety legislation, regulations, directives and other relevant guidelines 2. follow work instructions and specifications for the deposition process 3. ensure the material surfaces to be treated are prepared for the finishing operations 4. check that the finishing equipment and treatment solutions are set up and maintained at satisfactory operating conditions and levels 5. carry out the treatment process following operating procedures and to meet the component specification requirements 6. ensure that the treated workpiece achieves the required characteristics and meets the finishing specification 7. deal promptly and effectively with problems within your control and report those that cannot be solved 8. ensure that work records are completed, stored securely and available to others, as per organisational requirements 9. leave the work area in a safe condition on completion of the activities, as per organisational and legal requirements |
Knowledge and Understanding
You need to know and understand:
| 1. the specific safety precautions to be taken whilst carrying out the activities (including any specific legislation, regulations or codes of practice relating to the activities, equipment or materials) 2. the health and safety requirements of the work area and the activities, and the responsibility these requirements place on you 3. the hazards associated with the activities, and how to minimise them and reduce risks 4. the personal protective equipment and clothing (PPE) to be worn during the activities 5. how to obtain and interpret the production documentation required during the coating activity 6. the basic principles of the operation of physical or chemical vapour deposition equipment 7. the visual checks to be made on components prior to coating 8. the methods used to hold/secure components during the coating process 9. the importance of monitoring the equipment settings during the physical or chemical vapour deposition process 10. the types of adjustment that can be made to equipment settings to maintain component quality 11. how to identify physical or chemical vapour deposition process faults (including incomplete coating, missed coatings and poor colour) 12. the basic quality checks to be carried out on physical or chemical deposition coated components 13. the importance of keeping the coating plant and equipment clean and free from contamination 14. how to pack and store finished components to avoid damage 15. the importance of completing the production documentation throughout the deposition process 16. the extent of your own responsibility and whom you should report to if you have problems that you cannot resolve 17. how to access, use and maintain information to comply with organisational requirements and legislation |
