कवच कठिणीकरण
- कवच कठिणीकरण ही एक पद्धत आहे ज्याचा वापर कमी कार्बन असलेल्या स्टीलच्या बाहेरील पृष्ठभागाला कडक करण्यासाठी केला जातो जेव्हा मध्यभाग किंवा अंतरक मऊ आणि लवचिक असतो.
- कवच कठिणीकरणामध्ये काही कार्बनी पदार्थामध्ये धातूला त्याच्या संपूर्ण तापमानापर्यंत गरम करणे आवश्यक असते.
- खालील पद्धती सामान्यतः पुढील कारणांसाठी वापरल्या जातात:
- पॅक पद्धत
- सायनायडिंग
- नायट्रायडिंग
- प्रेरण कठिणीकरण
- ज्वाला कठिणीकरण
नायट्राइडिंग:
- नायट्रायडिंग ही कवच कठिणीकरणाची प्रक्रिया आहे ज्यामध्ये स्टीलच्या पृष्ठभागावर कार्बनऐवजी नायट्रोजन जोडला जातो.
- अमोनिया वायू आणि वेगळ्या अमोनियाच्या वातावरणात नायट्रायडिंग स्टीलचा भाग 482-621°से (900-1,150°फॅ) पर्यंत गरम करते.
- या वातावरणात हा भाग किती वेळ घालवतो यावरुन कवचाची खोली ठरते.
- नायट्राइडिंगनंतर कोणतेही शमन केले जात नाही.
