pindalalise materjali suhe

Usage examples

Pindalalise materjali suhe (Smr(c)) on 3D-pinna metroloogiaparameeter, mis võimaldab mõõta antud sügavusel tahke materjali ristlõikepindala protsentuaalset materjali osakaalu, arvutatuna nn laagripinna ehk Abbott-Firestone'i kõvera abil, ja on oluline pinna toimivuse, nt tihenduse, määrimise või kulumiskindluse, hindamiseks.

areal material ratio

Usage examples

Areal material ratio (Smr(c)) is a 3D surface metrology parameter that measures the percentage of a surface's cross-sectional area that is solid material at a given depth, calculated using an Abbott-Firestone (bearing area) curve. It is essential for determining surface performance, such as sealing, lubrication, or wear resistance.
