Description
・金属成形体
図2に示すように、リン青鋼に膜厚2μmの金メッキをした金属部品表面に対し、表1に記載した角度(角度θ)となるよう光軸を設定し、レーザー照射して金属部品表面に凹部を形成した。その際、レーザー照射は、Cobra,Electrox社製(レーザタイプ:継続波/Qswich付Nd:YAG、発振波長:1.064μm、最大定格出力:20W(平均))を用いた。レーザー照射は、当該照射によりドット状に形成された凹部の開口径が30μm、深さが40μmとなるよう調整した。なお、開口径、凹部深さはレーザー顕微鏡(株式会社キーエンス社製、「VK−9510」)を用いて測定した。金属表面のレーザー照射跡は、ドット状に形成された凹部を連続して形成して、略平行に並ぶ複数の直線状に照射跡を形成した後、90度回転した方向に略平行に並ぶ複数の照射跡とを交差させて、網目状になるよう形成した(図3)。
金属成形体を射出成形用の金型内に配置し、ポリフェニレンスルフィド樹脂(DIC.PPS Z−230)を竪型射出成形機(ソディック社製「TR−40VR」、シリンダ温度335℃、金型温度85℃、保圧力600kg/m2、射出速度100mm/s)を用いて射出成形して、金属樹脂接合成形品を製造した(図4)。
得られた金属樹脂接合成形品を接合面に対し垂直方向に引っ張り、25℃、150℃雰囲気下で、ISO527に準拠した引っ張り強度試験を実施し、得られた最大応力値を密着強度〔MPa〕とした。
得られた金属樹脂接合成形品に対して、−40℃⇔150℃の冷熱1000サイクルを与えた後、25℃雰囲気下で、測定法1と同様にISO527に準拠した引っ張り強度試験を実施した。
