Description

本発明は、いわゆる押し込み法によって試料の硬度を測定する微小硬度計、及び、これを用いた硬度測定方法に関する。   The present invention relates to a microhardness meter that measures the hardness of a sample by a so-called indentation method, and a hardness measurement method using the same.

この種の従来の微小硬度計としては、特許文献１及び特許文献２に開示されたものがある。特許文献１及び特許文献２の微小硬度計は、試料の表面に押し込む圧子と、押し込む際の圧子の押圧力（試験力）、変位量等を検出する検出部と、この検出部の検出結果より硬度を算出する算出部とを備えている。圧子の先端部は、三角錐等の角錐にて形成されている。この角錐の圧子の先端を試料に押し込み、その際の圧子の押圧力と変位量に基づいて試料の硬度を測定する。
特開昭６１−１９３０４７号公報 特開昭６２−６９１４１号公報 As this type of conventional microhardness meter, there are those disclosed in Patent Document 1 and Patent Document 2. The micro hardness tester of Patent Document 1 and Patent Document 2 includes an indenter that is pushed into the surface of the sample, a detection unit that detects the pressing force (test force) of the indenter when the sample is pushed in, a displacement amount, and the detection result of the detection unit.

JP-A-61-193047 JP 62-69141 A

しかしながら、特許文献１及び特許文献２に開示された微小硬度計は、いずれも圧子の先端が点接触で試料を押圧する。そのため、比較的軟らかい試料、表面に微小な凹凸がある試料、硬度の異なる含有物が含まれる試料の場合には、測定結果に大きなバラツキが出る。   However, in each of the microhardness meters disclosed in Patent Document 1 and Patent Document 2, the tip of the indenter presses the sample by point contact. Therefore, in the case of a sample that is relatively soft, a sample that has minute irregularities on the surface, or a sample that contains inclusions with different hardnesses, the measurement results vary greatly.

つまり、比較的軟らかい試料では、圧子の先端が試料の表面に食い込んだり、また、圧子の試料に対する押圧を解除する際に圧子の先端が試料に接着したりし、これらが原因で測定結果に大きなバラツキが出ると考えられる。表面に微小な凹凸がある試料では、圧子の先端が試料の表面の凹部を押圧する場合と凸部を押圧する場合で変位量が相違し、これによって測定結果に大きなバラツキが出ると考えられる。硬度の異なる含有物が含まれる試料では、圧子の先端が含有物を押圧する場合と、含有物以外の箇所を押圧する場合とで変位量が相違し、これによって測定結果に大きなバラツキが出ると考えられる。このような測定結果のバラツキが大きいと、試料の平均的な硬度を正確に測定できない。   In other words, in the case of a relatively soft sample, the tip of the indenter bites into the surface of the sample, or the tip of the indenter adheres to the sample when releasing the pressure of the indenter against the sample. It is thought that there will be variations. In a sample having minute irregularities on the surface, it is considered that the amount of displacement differs between when the tip of the indenter presses a concave portion on the surface of the sample and when the convex portion presses, and this causes a large variation in measurement results. In samples containing inclusions with different hardness, the amount of displacement differs between the case where the tip of the indenter presses the inclusion and the case where the tip other than the inclusion is pressed, and this results in large variations in the measurement results. Conceivable. If the variation in measurement results is large, the average hardness of the sample cannot be measured accurately.

そこで、本発明は、試料の種類に関わらず測定バラツキを極力小さくできる微小硬度計及び硬度測定方法を提供することを目的とする。   Accordingly, an object of the present invention is to provide a microhardness meter and a hardness measurement method capable of minimizing measurement variations regardless of the type of sample.

上記目的を達成する請求項１の発明は、試料の表面に押し込む圧子を備え、前記圧子の先端部には、所定値以上の面積を有し、且つ微小な凹凸が形成された微小凹凸面が設けられたことを特徴とする微小硬度計である。   The invention of claim 1 that achieves the above object comprises an indenter that is pushed into the surface of a sample, and a micro uneven surface having an area of a predetermined value or more and having micro unevenness formed at the tip of the indenter. A microhardness meter characterized by being provided.

請求項２の発明は、請求項１記載の微小硬度計であって、前記微小凹凸面は、半径１ｍｍ以上の円形に形成されたことを特徴とする微小硬度計である。   The invention according to claim 2 is the micro hardness tester according to claim 1, wherein the micro uneven surface is formed in a circular shape having a radius of 1 mm or more.

請求項３の発明は、請求項１又は請求項２記載の微小硬度計であって、前記微小凹凸面は、中心線平均荒さが０．５ａ〜５．０ａの範囲に設定されたことを特徴とする微小硬度計である。   The invention according to claim 3 is the micro hardness tester according to claim 1 or 2, wherein the micro uneven surface has a center line average roughness set in a range of 0.5a to 5.0a. It is a micro hardness tester.

請求項４の発明は、請求項１〜請求項３のいずれか１項記載の微小硬度計であって、前記圧子は、アルミニウム材にて形成されたことを特徴とする微小硬度計である。   A fourth aspect of the present invention is the microhardness meter according to any one of the first to third aspects, wherein the indenter is made of an aluminum material.

請求項５の発明は、請求項１〜請求項４のいずれか１項記載の微小硬度計であって、前記試料は接着剤であることを特徴とする微小硬度計である。   The invention according to claim 5 is the microhardness meter according to any one of claims 1 to 4, wherein the sample is an adhesive.

請求項６の発明は、先端部に所定値以上の面積を有し、且つ微小な凹凸が形成された微小凹凸面が設けられた圧子を備えた微小硬度計によって、前記圧子を硬化中の接着剤の表面に押し込み、押し込んだ際の押圧力と変位量に基づいて前記接着剤の時間経過に伴う硬化度を測定することを特徴とする微小硬度計を用いた硬度測定方法である。   The invention according to claim 6 is characterized in that the indenter is bonded during curing by a microhardness meter including an indenter having an area of a predetermined value or more at a tip portion and provided with a micro uneven surface on which micro unevenness is formed. It is a hardness measurement method using a microhardness meter, characterized in that the degree of cure of the adhesive with the passage of time is measured on the basis of the pressing force and displacement when the adhesive is pushed into the surface of the agent.

請求項１の発明によれば、圧子の先端が多数の点接触で試料を押圧するため、比較的軟らかい試料の場合には圧子の多数の凸部が試料の表面を分散して押圧し、また、表面に微小凹凸がある試料の場合には圧子が表面の凸部と凹部を共に押圧し、更に、含有物が含まれている試料の場合には圧子が含有物の箇所とそうでな箇所を共に押圧することから測定結果に大きなバラツキが出ない。以上より、試料の種類に関わらず測定バラツキを極力小さくできる。換言すれば、試料の平均的な硬度を正確に測定できる。   According to the invention of claim 1, since the tip of the indenter presses the sample by a number of point contacts, in the case of a relatively soft sample, a large number of convex portions of the indenter disperse and press the surface of the sample. In the case of a sample with minute irregularities on the surface, the indenter presses both the convex and concave portions on the surface, and in the case of a sample containing inclusions, the indenter is the location of the inclusion and the location where it seems The measurement results do not vary greatly because they are pressed together. As described above, measurement variations can be minimized as much as possible regardless of the type of sample. In other words, the average hardness of the sample can be measured accurately.

図１に示すように、微小硬度計１は、硬度計本体２と、この硬度計本体２に進退自在に支持された圧子３と、圧子３に試料への押し込む力（以下、試験力）を作用させる試験力作動手段４と、試験力作動手段４等を制御する制御手段５と、圧子３の変位量を検出する変位量検出手段６と、試験力作動手段４からの試験力と変位量検出手段６からの変位量に基づいて仕事量を算出し、算出した仕事量より硬度（仕事量と硬度は比例関係）を導き出す演算部７とを備えている。   As shown in FIG. 1, the micro hardness tester 1 includes a hardness tester main body 2, an indenter 3 supported by the hardness tester main body 2 so as to freely advance and retreat, and a force (hereinafter referred to as a test force) for pushing the sample into the indenter 3. Test force actuating means 4 to be applied, control means 5 for controlling the test force actuating means 4 and the like, displacement amount detecting means 6 for detecting the displacement amount of the indenter 3, and test force and displacement amount from the test force actuating means 4 A work amount is calculated based on the amount of displacement from the detection means 6, and a calculation unit 7 is provided that derives the hardness (the work amount and the hardness are proportional to each other) from the calculated work amount.

圧子３はアルミニウム材にて形成され、円柱形状を有する。圧子３の先端面は、図２（ａ）、（ｂ）に示すように、半径１ｍｍの円形状の大きさで、且つ、微小凹凸面３ａに形成されている。微小凹凸面３ａの中心線平均荒さＲａは、０．５ａ〜５．０ａの範囲に設定されている。ここで、中心線平均荒さＲａは、ＪＩＳ（Ｂ０６０１〜１９９４）によってＬ×∫｛０〜Ｌ｝│ｆ（ｘ）│ｄｘで定義される物理量である。   The indenter 3 is formed of an aluminum material and has a cylindrical shape. As shown in FIGS. 2A and 2B, the tip surface of the indenter 3 has a circular shape with a radius of 1 mm and is formed on the minute uneven surface 3a. The center line average roughness Ra of the minute uneven surface 3a is set in a range of 0.5a to 5.0a. Here, the centerline average roughness Ra is a physical quantity defined by L × ∫ {0−L} | f (x) | dx according to JIS (B0601-1994).

次に、上記微小硬度計１を用いた硬度測定方法を説明する。今回の測定では、試料は比較的軟らかい物質である接着剤１０とし、接着剤１０の塗布直後から時間経過に伴う硬化度を測定する。   Next, a hardness measurement method using the micro hardness tester 1 will be described. In this measurement, the sample is the adhesive 10 which is a relatively soft material, and the degree of cure with time is measured immediately after application of the adhesive 10.

測定手順は、接着剤１０の複数箇所を測定ポイントとし、各測定ポイントに対して圧子３の押し込みによる硬度測定を行う。圧子３の押し込みは、具体的には、図３に示すように、圧子３の接着剤１０への押し込み力をゼロから徐々に大きくして最終的に最大試験力を作用させ（負荷区間）、その後、最大試験力を一定時間保持し（保持区間）、その後、圧子３の試験力を徐々に弱くし、最終的に試験力をゼロとする（徐荷区間）押し込み手順で行う。そして、この押し込みの各区間の変位量を連続的に測定して図４に示す試験力−変位量の測定データを得る。図４の試験力−変位量の特性線で囲まれる面積より仕事量を算出する。この算出した仕事量は硬度に比例するため、算出した仕事量のバラツキ程度より硬度計１を評価する。バラツキの程度は、測定されたデータを偏差値化して判定する。   The measurement procedure uses a plurality of locations of the adhesive 10 as measurement points, and performs hardness measurement by pressing the indenter 3 at each measurement point. Specifically, as shown in FIG. 3, the indenter 3 is pushed in by gradually increasing the pushing force of the indenter 3 into the adhesive 10 from zero and finally applying the maximum test force (load section). Thereafter, the maximum test force is held for a certain time (holding section), and thereafter the test force of the indenter 3 is gradually weakened, and finally the test force is set to zero (gradual load section). And the displacement amount of each section of this pushing is continuously measured, and the test force-displacement amount measurement data shown in FIG. 4 is obtained. The work amount is calculated from the area surrounded by the test force-displacement characteristic line in FIG. Since the calculated work amount is proportional to the hardness, the hardness meter 1 is evaluated from the degree of variation of the calculated work amount. The degree of variation is determined by converting the measured data into deviation values.

試料の接着剤１０としては、図５に示すように、サンプル１，サンプル２，サンプル３を用意し、各サンプルにおける試験力の作用条件は、図６に示す値とした。   As the sample adhesive 10, as shown in FIG. 5, Sample 1, Sample 2, and Sample 3 were prepared, and the operating condition of the test force in each sample was the value shown in FIG.

以上説明した測定条件の下、サンプル１，サンプル２，サンプル３について本発明に係る圧子３と従来例に係る圧子を用いて測定を行い、図７〜図９の結果を得た。図７〜図９において、実線の○印は本発明に係る圧子３の代表的なデータであり、×印は従来例に係る圧子（ベルコビッチ三角錐で、頂角６５度）のデータであり、仮想線の○印は本発明に係る圧子３の標準偏差の範囲の大きさを示す。   Under the measurement conditions described above, Sample 1, Sample 2, and Sample 3 were measured using the indenter 3 according to the present invention and the indenter according to the conventional example, and the results of FIGS. 7 to 9 were obtained. 7 to 9, the solid circles are representative data of the indenter 3 according to the present invention, and the x marks are data of an indenter according to the conventional example (Belkovic triangular pyramid, apex angle 65 degrees), A circle in the imaginary line indicates the size of the standard deviation range of the indenter 3 according to the present invention.

図７〜図９等の測定結果より、本発明に係る圧子（実地例１〜５）と従来例に係る圧子（比較例１〜３）の測定バラツキの標準偏差値を導くと、図１０に示す結果が得られた。測定バラツキの偏差値は｛測定データ／（全ての測定データの平均値）｝×１００の演算式より求められる。測定バラツキの偏差値は、平均値よりどの程度ずれているかを示す指標であり、数値が小さいほどバラツキ量が小さいことを示すことになり、実地例１〜５が比較例１〜３に較べて十分にバラツキ量が小さいことが実験より確かめられた。   From the measurement results of FIGS. 7 to 9 and the like, when the standard deviation values of the measurement variations of the indenter (actual examples 1 to 5) according to the present invention and the indenter according to the conventional example (comparative examples 1 to 3) are derived, FIG. The results shown are obtained. The deviation value of the measurement variation is obtained from an arithmetic expression of {measurement data / (average value of all measurement data)} × 100. The deviation value of the measurement variation is an index indicating how much the deviation is from the average value. The smaller the numerical value, the smaller the variation amount, and the practical examples 1 to 5 are compared with the comparative examples 1 to 3. It was confirmed from experiments that the amount of variation was sufficiently small.

つまり、本発明によれば、圧子３の先端面は、半径１ｍｍの大きさで、且つ、微小凹凸面３ａに形成されているので、圧子３の先端が多数の点接触で接着剤１０の表面を押圧するため、圧子３の多数の凸部が接着剤１０の表面を分散して押圧することから測定結果に大きなバラツキが出ない。   That is, according to the present invention, the tip surface of the indenter 3 has a radius of 1 mm and is formed on the minute uneven surface 3a. Since the large number of convex portions of the indenter 3 disperse and press the surface of the adhesive 10, the measurement result does not vary greatly.

また、表面に微小凹凸がある試料の場合には圧子３が表面の凸部と凹部を共に押圧し、また、含有物が含まれている試料の場合には圧子３が含有物の箇所とそうでな箇所を共に押圧することから測定結果に大きなバラツキが出ないことが容易に推測できる。以上より、試料の種類に関わらず測定バラツキを極力小さくできる。換言すれば、試料の平均的な硬度を正確に測定できる。   In addition, in the case of a sample having minute irregularities on the surface, the indenter 3 presses both the convex and concave portions on the surface, and in the case of a sample containing inclusions, the indenter 3 is the location of inclusions. It can be easily estimated that there is no large variation in the measurement results because the large parts are pressed together. As described above, measurement variations can be minimized as much as possible regardless of the type of sample. In other words, the average hardness of the sample can be measured accurately.

本実施形態では、微小凹凸面３ａは、半径１ｍｍの大きさであるので、十分な面積を持って面接触するため、測定バラツキを確実に抑制できる。なお、本実施形態では、微小凹凸面３ａが半径１ｍｍの面積を有するが、それ以上の面積を有するものであっても良い。また、微小凹凸面３ａの形状も円形以外であっても良いことはもちろんである。   In the present embodiment, since the minute uneven surface 3a has a radius of 1 mm, the surface contact is made with a sufficient area, and therefore measurement variations can be reliably suppressed. In the present embodiment, the fine uneven surface 3a has an area with a radius of 1 mm, but may have an area larger than that. Of course, the shape of the minute uneven surface 3a may be other than circular.

本実施形態では、微小凹凸面３ａは、中心線平均荒さが０．５ａ〜５．０ａの範囲であるので、図１０に示すように、測定バラツキを有効に抑制できる。   In the present embodiment, since the minute uneven surface 3a has a center line average roughness in a range of 0.5a to 5.0a, measurement variation can be effectively suppressed as shown in FIG.

なお、本実施形態では、圧子３は、試料である接着剤よりも十分に硬く、金属の中では比較的柔らかいアルミニウム材にて形成されているので、圧子３の先端面を容易に加工できる。なお、圧子３の少なくとも先端部は、ダイヤモンド、ステンレス鋼、超硬度鋼にて形成しても良い。   In the present embodiment, since the indenter 3 is sufficiently harder than the adhesive as a sample and is formed of a relatively soft aluminum material among metals, the tip surface of the indenter 3 can be easily processed. Note that at least the tip of the indenter 3 may be formed of diamond, stainless steel, or superhard steel.

また、本実施形態の微小凹凸面３ａは、平滑面に所定の間隔で突起が無数に形成された部材によって傷つけることで、微小な凹凸が形成されているが、平滑面に所定の間隔で、三角錐、四角錐、円錐等の突起を形成することで、微小な凹凸を設けても良い。   In addition, the minute uneven surface 3a of the present embodiment is formed with minute unevenness by being damaged by a member in which projections are formed innumerably at predetermined intervals on the smooth surface, but at a predetermined interval on the smooth surface, Minute irregularities may be provided by forming protrusions such as a triangular pyramid, a quadrangular pyramid, and a cone.

本実施形態では、比較的軟らかい物質である接着剤１０を試料としたが、試料の硬度の程度は問わない。しかし、上述したように本発明に係る圧子３は従来の圧子ではバラツキの大きな硬度測定しかできない試料について特に有効である。   In the present embodiment, the adhesive 10 which is a relatively soft material is used as a sample, but the degree of hardness of the sample is not limited. However, as described above, the indenter 3 according to the present invention is particularly effective for a sample in which the conventional indenter can only measure hardness with large variations.
