(1) Isithando somlilo sikagesi sisebenzisa ugesi, umthombo wamandla ohlanzeke kunawo wonke. Eminye imithombo yamandla njengamalahle, i-coke, uwoyela ongahluziwe, igesi yemvelo, njll. nakanjani izoletha izici ezihambisana nokungcola enqubweni yokusansimbi. Izithando zomlilo zikagesi kuphela ezingakhiqiza ama-alloys ahlanzekile.
(2) Ugesi uwukuphela komthombo wamandla ongathola izimo zokushisa eziphakeme ngokunganaki.
(3) Isithando somlilo sikagesi singabona kalula izimo ze-thermodynamic ezifana ne-oxygen partial pressure kanye ne-nitrogen partial pressure edingwa ukusabela okuhlukahlukene kwe-metallurgical njengokunciphisa, ukucwengwa kanye ne-nitriding.
