ni-hard
1.The abrasive resistance of as-cast martensitic high chromium cast iron is 3 times more than that of Ni-hard cast iron.
2.A research was conducted to study the carbide structure and morphology of common, Ni-hard, high chrcmium arid bcron white cast irons by means of TEM, SEM, SIMS and X-ray diffraction using deep-corrosion technique and particular samples.
3.Ni-SiC composife coatings have higher resista-noe properties to wear than hard Chromium coatings. Mechanism of the Ni-SiCcodeposits is also discussed.
4.The Study of Precipitation Phase of Semi-hard Fe-Ni-AI-Ti Magnetic Alloy in the Tempering Procese
5.Determination resulted that hard ness of Ni-P deposit was between 290～490 HV and it decreased with increase of bri ghtener content.
