Ho thatafala ha phala ea tšepe ho bolela bokhoni ba thepa ea ho hanyetsa deformation tlas'a matla a ka ntle. Ho thatafala ke e 'ngoe ea matšoao a bohlokoa a ts'ebetso ea thepa.
Ha ho etsoa le ho sebelisoa liphaephe tsa tšepe, boikemisetso ba boima ba bona ke ba bohlokoa haholo. Ho thatafala ha lipeipi tsa tšepe ho ka lekanyetsoa ka lisebelisoa tse fapaneng tse lekang ho thatafala tse kang Rockwell, Brinell, le Vickers tse hlahisoang ke Laizhou Laihua Testing Instrument Factory, e ka etsoang ha ho hlokahala. Mekhoa e meholo ea ho lekanya e kenyelletsa tse latelang:
1. Mokhoa oa ho hlahloba boima ba Rockwell
Hona joale tlhahlobo ea boima ba Rockwell ke mokhoa o sebelisoang ka ho fetisisa, oo HRC e leng oa bobeli feela ho Brinell hardness HB ka tekanyo ea pipe ea tšepe. E lekanya botebo ba ho indentation mme e ka sebelisoa ho lekanya lisebelisoa tsa tšepe ho tloha ho tse bonolo haholo ho isa ho tse thata haholo. E bonolo ho feta mokhoa oa tlhahlobo ea Brinell.
2. Mokhoa oa ho hlahloba boima ba Brinell
Mokhoa oa tlhahlobo ea boima ba Brinell o boetse o sebelisoa haholo lefapheng la indasteri. E sebelisoa haholo ka litekanyetso tsa liphaephe tsa tšepe tse se nang moeli. Ho thatafala ha thepa hangata ho bontšoa ke bophara ba indentation. E bonolo ebile e bonolo, empa ha e sebetse ho lipeipi tsa tšepe tse thata kapa tse tšesaane.
3. Mokhoa oa ho hlahloba boima ba Vickers
Teko ea boima ba Vickers e boetse e sebelisoa haholo. E na le melemo ea mantlha ea mekhoa ea tlhahlobo ea Brinell le Rockwell, empa e hlola mefokolo ea bona ea mantlha. E loketse tlhahlobo ea boima ba lisebelisoa tse fapaneng, empa ha e loketse lisampole tse nang le li-diameter tse nyane. Ha e bonolo joalo ka mokhoa oa tlhahlobo ea Rockwell mme ha e sebelisoe hangata maemong a lipeipi tsa tšepe.
