2.2 Ukumatsheka kobuso kanye nemiphumela yokukala ubulukhuni Ubulukhuni obungaphezulu bevalvu yenaliti iyalinganiswa, futhi imfuneko yokuhwaqazeka kwendawo yevalvu yenaliti ingu-61HRC～65HRC ngemfuneko yokuqina kwendawo. Ubulukhuni bevalve yenaliti enenombolo yesitembu sensimbi i-HHM ngu-Ra0.03, Rt0.34, futhi ukuqina kwendawo kungu-60.4HRC～60.7HRC; ivalve yenaliti enenombolo yesitembu sensimbi HD yi-Ra0.02, Rt0.37, futhi ukuqina kwendawo kungu-62.3HRC. Ubulukhuni nobulukhuni bamavalvu enaliti amabili alethwe ukuze ahlolwe wonke ahlangabezana nezidingo zokuklama. Ngemuva kokuthi i-nozzle ihlakaziwe, ubulukhuni bembobo yangaphakathi kukalwa. Imfuneko yobuhwaqane bembobo yangaphakathi yombhobho yayingu-0.05Rt0.8. I-Valve Ra0.07–1.16, Rt0.82–1.79. Ubulukhuni bembobo bangaphakathi bemibhobho emibili ethunyelwe ukuze buhlolwe abuhlangabezananga nezidingo zokuklama.

2.3 Isilinganiso sokuqina kobuso kanye nemiphumela yokuhlaziya i-metallographic Ukuqina kwendawo yevalvu yenaliti kuyadingeka ukuthi kube ngu-61HRC-65HRC, i-bainite yamahhala ayivunyelwe, futhi i-austenite esele ingeqi ku-5%. Ukuqina kwevalvu yenaliti enenombolo yesitembu sokuqala esithi HHM ngu-62.9HRC～63.6HRC, usayizi wokusanhlamvu ngu-10, kanye nezinga lokushisa okuphezulu ngu-2; ukuqina kwevalvu yenaliti enenombolo yokuqala yesitembu sensimbi HD ngu-62.4HRC～63.4HRC, usayizi wokusanhlamvu ngu-9, futhi izinga lokushisa eliphakeme lingu-2. Ukuqina kwamavalvu enaliti amabili konke kuhlangabezana nezidingo zokuklama.
