Abstract
The invention discloses a process method for manufacturing a metallographic specimen, which comprises the following steps: a) quickly grinding a saw-cut specimen, wherein a spectrum-decommissioning specimen grinding machine changed into an abrasive wheel grinding plate is used; and a specimen grinding fixture which can clamp 8 to 10 specimens once is utilized to quickly grind the specimens and is manually held to quickly grind the specimens on the specimen grinding machine until surface roughness reaches to Ra 1.6 to 0.8 microns so as to meet the requirements on precise grinding; b) performing metallographic specimen grinding; and c) performing metallographic polishing. Compared with the prior art, the process method for manufacturing the metallographic specimen in the invention has the advantages of conveniently and quickly manufacturing the metallographic specimen, and not only ensuring the specimen manufacturing quality and analysis quality, but also saving the cost and improving the efficiency.
Description
Technical field
The present invention relates to the process that a kind of metallographic specimen is made.
Background technology
The making of metallographic specimen (grind, polish, handle) accounts for 2/3 of metallographic examination T.T., how to improve metallographic sample preparation efficient and has crucial meaning.
Traditional metallographic sample preparation adopts manual grinding, efficient is lower, sample behind the machinery, need ask through accurate flour milling (being plain grinding), microscopic examination personnel spread abrasive paper for metallograph on glass plate, carry out the 4-5 road by hand grinds, and the sand paper grade is more and more thinner, from (180#-) 240#-400#-600#-800# grinding successively, meticulous grind away need increase to 1000# even 1200#, and one sand paper of every replacing, need clear up sample, table top simultaneously.Grind after operation finishes, carry out rough polishing and finishing polish.Like this, the whole flow processs of sample are got off to spend 0.5h approximately and are completed.
Summary of the invention
Technical matters to be solved by this invention is, at above-mentioned prior art present situation, and the process that provides a kind of efficient height, the measured metallographic specimen of matter to make.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: the process that a kind of metallographic specimen is made, it is characterized in that, and comprise the steps:
A) sawing sample rapid stock-removal: use the retired sample grinding machine of spectrum that changes Grinding wheel disc mill into, but with the quick grind away of Clamping apparatus for polishing specimen of clamping 8-10 sample once, the manual gripping carried out rapid stock-removal on sample grinding machine, surfaceness reaches the requirement of accurate grinding to Ral.6-0.8um;
B) metallographic grind away: adopt metallographic grinding and polishing machine, can realize stepless change; The employing ratio is 1: 2 the anhydrides rigidizer and the cold resin of inlaying of epoxy group aliphatic resin composition, fills the groove of grinding and polishing machine mill, reaches the suitable hardness of grind away, and sand grains is difficult for scuffing sample face in grinding simultaneously; Carry out integrated poured back maintenance level, leave standstill and solidify after 24 hours, the resin sclerderm of spill-over is polished with fine sandpaper; On metallographic grinding and polishing machine, on the resin plane, smear higher vaseline of viscosity or butter to paste waterproof abrasive paper, in order to offset the friction force in the grind away;
Use the grinding of 400# sand paper after 1.5 minutes, add clear water cleaning sample with dish detergent; Re-use 800# or 600# sand paper, fine ginding 1.5 minutes;
C) metallurgical polishing: use the fine-grinding and polishing cloth of 3 micron dimensions, rough polishing suspending liquid to polish; Use general polishing cloth, the polishing suspending liquid of 3 micron dimensions to polish; Use finishing polish cloth, the finishing polish suspending liquid of 1 micron dimension to polish; Use the super finishing polish cloth of 0.04 micron dimension, super finishing polish suspending liquid to polish.
In the step b), can use 800# or 600# fine ginding after 1.5 minutes, re-use 1000# sand paper, fine ginding 1.5 minutes;
In the step c), in the super finishing polish cloth that uses 0.04 micron dimension, the polishing of super finishing polish suspending liquid.
Compared with prior art, the invention has the advantages that it can carry out metallographic sample preparation work easily and quickly, the whole flow processs of sample are got off to spend approximately ten minutes and are completed, both guarantee sample quality, analyzed quality, cost-saved again, improved efficient greatly.
